Bel-Ray products have a reputation for being best in class when it comes to quality performance and
innovative technology. The demands of current and next generation mining equipment mandates superior lubri-cants formulated to ensure the best protection and performance.
Bel-Ray’s top tier open gear lubricant: Molylube SF-100 Semi-Synthetic Open Gear Lubricant is designed to meet and exceed the most demanding applications and OEM specifications. The value and performance of the product has been proven around the world in the most challenging and harshest environments. The confidence and strong following SF-100 has in the mining community comes down to the simple fact that it reduces wear, extends component life and reduces total cost of ownership.
Molylube SF-100 is a top tier grease-type open gear lubricant. There are seven grades of SF-100 formulated for applica-tion temperature range between -50C and +50C. Regardless of the grade, the same performance qualities are present: excel-lent load carrying capability, reduce wear, reduces equipment operating tempera-tures and energy consumption.
A very recent case study helps illustrate the benefits of converting to SF-100.A Canadian mining customer expressed interest in evaluating SF-100 on two P&H 4100XPC-AC rope shovels. The customer was experiencing rapid wear on the saddle block wear plates on these shovels. The goal of our project with this customer was to extend the service life of the saddle block wear plates by convert-ing the customer to SF-100. We were confident that once we could demon-strate the superior performance of the product on these two shovels the entire fleet of shovels would be converted.
In order to conduct proper testing new saddle block wear plates were installed and
the rope shovels were properly converted. The conversion process included ensuring there were no compatibility issues with the existing open gear lubricant, pre-lubing the components with SF-100, and introducing the SF-100 into the centralized lubrication system. Once the shovels were back in operation SF-100 quickly established a heavy and durable lubricating film on all parts and assemblies to which it was being applied including the saddle block and dip-per handle assemblies.
The shovels in question have far exceed-ed the upper limit of the operating hour range at which the mine had been rou-tinely changing the excessively worn wear plates. Wear rates of the wear plates has been significantly reduced. We invited the original equipment manufacturer out to inspect and provide their opinion on the
performance of the SF-100 related to their rope shovel. The concluding comment of the OEM representative was that overall lube performance was excellent and wear rate is significantly improved after convert-ing to the Bel-Ray product. This customer was previously changing out wear plates every 800-1,200 hours. Bel-Ray customers around the world have achieved wear plate change intervals at 8,000-12,000 hours. The test is ongoing however we are confi-dent that we will see a massive increase on wear plate life based on proven perfor-mance we have experienced in the field. It speaks volumes that just a few months into our testing the customer converted their entire rope shovel fleet to the Molylube SF-100 Semi-Synthetic Open Gear Lubricant based on the results and perfor-mance they had observed.

Proximity detection systems on mobile mining machinery to help reduce accidents have become an industry-
driven initiative. Strata Worldwide has over 1000 HazardAvert® systems under-ground and at the surface currently oper-
ating in mines around the world. These global operations have chosen to incorpo-rate the technology into their safety pro-cedures.
No matter the application, HazardAvert creates an electromagnet field around
machinery that interacts with a miner-worn personal alarm device, or PAD. It creates a two-way communication between the person and the machine. As an individual or vehicle breaches this field, warning alarms alert the machine operator(s) and the individual. If a person or vehicle gets into a dangerous position, HazardAvert can be programmed to dis-able the machinery completely.
“There was an event in South Africa recently where a continuous miner opera-tor, standing in an intersection became dizzy and fell,” explains Mike Berube, president and COO of Strata Worldwide. “A co-worker immediately rushed to his aid, as he had fallen directly in the path of an approaching shuttle-car. The shuttle-car operator was not aware of the two individuals until the HazardAvert system detected them and stopped the machine.”
HazardAvert is a close-range proximi-ty detection system that has been success-fully used on both production and haul-age-type machinery at underground and surface mine locations.

6 Spring 2014 New Mining Technology
The mining industry is currently in a phase where innovation is quickly turning tip-of-the-spear technologies
into disruptive new capabilities that pres-ent opportunities for strong differentia-tion and massive leaps in efficiency.
One such area is related to the increas-ing sophistication of capabilities that drones provide. Drones or unmanned aerial vehicles (UAVs) are either human-
assisted or independent vehicles that per-form activities while flying or hovering above the ground.
While drones have been around for some time, the rapid development in affordable, lightweight, highly manoeu-vrable drones equipped with the latest mining-related technologies has opened up a whole new range of opportunities for possible applications.
The Mine of the FutureLet’s return to the Mine of the Future—circa 2020—where drones are playing an integral role right across the value chain, both on and offsite, delivering value in the areas of exploration and development, safety and security and operational pro-ductivity.
Among the planes at a regional mine airport, the newest member of FutureMine’s
DRONES DELIVER

team is taxiing from its secure facility onto the runway and is about to take off and go to work for the day.
Back in the office at the Remote Operations Centre (ROC), a drone’s con-troller is manoeuvering it into position and liaising with air traffic control also for take-off.
Drones are now regulars in air space and are monitored under air traffic con-trol protocols. Today’s schedule is a busy one. The controller has already been col-laborating with the exploration team at the ROC to confirm today’s exploration and analysis activities and is now ready to deliver.
Sensors and processing equipment drastically smaller in size and exponen-tially more powerful compared to today’s equipment is now standard on-board drones including chemical, electromag-netic, gamma ray and biological sensors.
After a few hours flying into inacces-sible terrain and 50 degree Celsius sum-mer temperatures, the drone reaches the target zone and starts to map and send back a live feed of multifaceted resource data—supported by real-time analytics delivering detailed maps and preliminary models to depth which the collaboration teams at the ROC analyse and develop further to determine where they will focus their resources and planning efforts.
After completing the work in a number of hours, the drone is on its way back when it is redirected to support condition moni-toring activities of a critical gas pipeline supplying one of FutureMine’s remote sites.
ROC controllers are monitoring the predictive analytics on the asset and are highlighting emerging integrity issues and a potential disruption—they’d love some “eyes on the ground” to correlate the information with a visual.
Soon the drone is delivering a live video feed with a 3D integrity model of the pipeline at the sector in question, in addition to vibration and thermal data to the Asset Health Team at the ROC to sup-port their decision making.
Live video and sound filtering is not physically and financially achievable across a long, geographically dispersed asset, but with drones it can be done in a targeted way, in real time.
All in a day’s workThe next day at one of FutureMine’s mine sites, the on-site drone is being prepared for another busy day.
The first task of the day is monitoring the morning traffic speeds and road rules observance for the mine’s employees and contractors travelling to work along the public and mine lease road.
Real-time data drives real-time perfor-mance management through the ROC with interventions on offending drivers taking place early in their journey via radio or via traffic wardens, potentially reducing serious safety incidents as well as driving an improved safety culture.
From there, the drone is assigned to the Mine Rescue Team, who is conducting its regular exercises, simulating one of its diverse range of major safety incidents and exploring how it could more effec-tively respond through the use of drones.
The team has modelled a dangerous plant explosion and is looking to test its options to rapidly deliver medical supplies including oxygen, radios and burn blan-kets into a highly dangerous environment.
Conducting a wet run under simulated conditions, the onsite controller manoeu-vers a quad drone to safely and precisely deliver relief. At the same time, the drone is also able to take sensory readings on individuals for medical purposes and assess residual noxious gas levels to sup-port further response planning.
Still on site, the mining team now reassigns the drone to conduct a range of activities to improve its survey productiv-ity, accuracy and cost. The onsite control-ler directs the drone to map the stockpiles and mine face areas. The information is then used to support photogrammetry, or the use of photos to map a geometric area and accurately map the stockpiles.
This information is processed in real time enabling faster, more accurate gath-ering, processing and reconciliation of spatial data, supporting improved deci-sion making and lowering survey costs.
Once finished on the stockpiles, the drone is assigned to conduct basic time-lapse photography in a number of areas across the site value chain to monitor the shifting physical properties of key assets.
The combination of time-lapse photog-
raphy in conjunction with the sensory information set and predictive analytics enables the mine to closely monitor and safely manage large, geographically disperse assets that would benefit from aerial moni-toring—such as an enormous leach pad and tailings dam assets. This also supports the management to meet their environ-mental obligations across the operation.
For the last task of the day, the process-ing area has asked for the drone controller to conduct some preliminary observa-tions to support the planning of an upcoming shutdown. The team would like some physical observations on the condition of key assets which are difficult and dangerous to access while the plant is running. The highly skilled operator is able to successfully navigate the drone in narrow and dangerous places and is soon providing a comprehensive feed of live images in addition to sensory information back to the planners in the ROC on key equipment (such large tanks and oxygen plants) to support the planning efforts.
It’s been just another busy day for the versatile drone which has added signifi-cant value across the value chain at a modest cost. Who knows what tomorrow will bring?
Delivering ResultsThe possibilities for the application of drones in mining are seemingly endless with new uses coming to light every week and more widespread utilization being reported across the industry.
There are potential benefits across the value chain, from safety and security (e.g. search & rescue, monitoring / providing information from dangerous and difficult locations) to exploration & development (e.g. aerial photography and remote sens-ing) and productivity (e.g. stockpile map-ping, mine mapping & reconciliation and time lapse photography) just to name a few.
Leading mining businesses are rap-idly making these kinds of capabilities available through their use and custom-ization of drones. Turning these ideas into results of course requires coordi-nated planning across the value chain and focused execution. NMT

The mineral resource sector continues to be a mainstay of the Canadian economy. As more mineral deposits
and gas reserves are developed, safety con-cerns remain paramount. We already know that bacteria can influence certain mining processes. We also know that the successful practical applications of technologies exploiting biological processes can be an important contributor to future cost com-petitiveness, safety and environmental per-formance in the mining industry.
Living things in and around a mine site, from a tiny microbe to a lodgepole pine, have a genome that codes their bio-logical functions. Genomics aims to under-stand and apply this encoded information
to link changes in traits in response to the surroundings. Accordingly, current chal-lenges around biological processes in min-ing could be improved by genomics-based technologies by providing a new perfor-mance measure. Some examples include monitoring of effluent discharge; mitiga-tion of risks of environmental impact; test-ing toxicity for fish and wildlife; improving recovery of target minerals; extracting residuals from lower grade ores; identify-ing new deposits of interest; and increasing the robustness of remediation.
WATER PURIFICICATION & RECYCLINGSafety precautions around groundwater are of particular concern in the mining
industry: no one wants toxic compounds flowing into fish bearing streams and waterways. To meet optimal safety levels, mining companies use chemicals to treat dissolved metal and acid rock drainage. These treatments, while effective, are also expensive and produce their own byprod-ucts - which then must be carefully con-tained for years to come or treated further to ensure safety.
Bioremediation of wastewater is an area of growing interest: the process uses naturally occurring microbes that live in and around mine sites to ‘digest’ the toxic compounds and detoxify the contaminat-ed water. In essence, the specialized organisms thrive on toxic chemicals, inte-

grating them into their metabolism while neutralizing toxicity.
While bioremediation has been around for years, we are still learning how these toxin-digesting microbes work, how to best exploit their unique capabilities and how to optimize them to work better in challenging environments. Dr. Susan Baldwin, a professor in the University of British Columbia’s Chemical and Biological Engineering Department, is helping move the science towards applica-tion – making bioremediation a more economical and accessible option - by applying genomics.
The real benefit of applying genomics to bioremediation lies in the understand-ing we gain on how complex microbial communities living together in mine wastewater function and, more impor-tantly, what makes them flourish. In order for these microbes to function effectively, it is imperative we know what sort of envi-ronment best fosters them—the type of nutrients, food sources, and conditions that maximize the growth and function of the most desirable group of microbes.
Dr. Baldwin and her team are working to discover microbes with particular abili-ties to treat a wide variety of waste streams and to then develop bioreactors in which to grow and use these microbes. Microbes live in diverse environments, including those that are extreme with toxic metals, strong acids, sulfurous compounds and other chemicals. Dr. Baldwin looks for microbes thriving in these harsh environ-ments and transforms mine-related toxic compounds into more benign forms. Her efforts are also directed toward replicating conditions for optimum performance in full-scale bioreactors at mine sites.
Many mine sites can become long-term sources of environmental concern for liable companies and governments. For example, more than 6,000 abandoned mines have been identified in Ontario alone and other provinces face similar challenges. Bioremediation, or the har-nessing of natural communities of microbes to clean up a polluted site, can be a cost-effective solution to mitigating environmental effects at some of these sites. However, it is not yet completely clear why bioremediation is successful in some cases but fails in others. Providing a more thorough understanding of what
microbes can do is another example for the power of genomics-based technolo-gies and another instance where science helps to put safety first.
TOXICOGENOMICSIn another application, ‘omics technolo-gies, which include genomics as well as proteomics and metabolomics (informa-tion on all proteins and metabolites in an organism), are playing an important role in analyzing the toxicity of mine water discharge. Environmental contaminants are a safety concern not only for their direct impact on the ecosystem but also for longer-term and far-reaching effects.
Exposure to metals such as copper, zinc and cadmium can cause significant adverse effects so there is a need for rele-vant and precise predictors of biological outcome. Detection and identification of a potential pollutant is the first step in assessing toxicity but it is in no way a pre-dictor of biological outcome. Current fisheries management practices expose aquatic species to contaminants in labora-tories and assess toxicity based on death or survival of the exposed species.
Toxicogenomics decodes molecular level expression of toxicity in an organism, and provides biomarkers that predict toxic response or susceptibility to it. Dr. Graham van Aggelen, Head of the Environmental Toxicology Laboratory at Environment Canada’s Pacific Environmental Science Centre is developing toxicogenomics capacities and expertise. He sees the ulti-mate application in non-lethal testing of sentinel species such as Salmonids and Amphibians for a combination of toxins and under various exposure levels.
In collaboration with University of Victoria and the BC Ministry of Environment, van Aggelen published research last year in Aquatic Toxicology that described the feasibility of non-lethal sampling of fish fin for the determination of potentially harmful effects of a wide range of environmental contaminants using ‘omics tools.
Other innovations at the Environmental Toxicology Laboratory include analysis of gene and protein activity to determine whether the water sample meets standard quality database indicator limits, provid-ing a potential new tool for regulators and consultants. Van Aggelen’s work also offers insight into the level of impact mine development in a highly mineralized geo-logical area can make on resident popula-tions. Using genomics it is possible to track and model the effects of increased release of metals into a naturally impacted environment.
THE FUTURE OF ‘OMICS & MINING‘Omics are providing promising tools and there is a significant potential for industry-wide applications. Genome British Columbia, a non-profit research organiza-tion that invests in and manages large-scale genomics projects, is investing in research that aims to provide relevant and practical solutions to end-user operations to catalyze applications. Applied genomics research conducted in BC will not only provide benefits to the province, but is expected to be taken up by companies across Canada and around the world. NMT

High Odour Products Impair ProductivityLow Odour Maintenance Products Promote Healthy, Productive Work Environment
The profitability of a mine is dependent on its ability to reduce downtime, and improve productivity.
Unscheduled downtime is expensive and any reduction in downtime can pay dividends to the bottom line.
Increasing productivity is a never end-ing struggle in the resource mining sector and can often involve confusing and dif-ficult to implement solutions.
If the introduction of a product involves both reduced downtime and increased productivity, the entire mining industry listens.
Henkel recently introduced a new gen-eration of Nordbak crusher backing com-pound that promises exactly that; reduced downtime, and increased productivity.
Loctite Nordbak PC 9020 is a new low odour, high performance backing com-pound formulated with the use of new advanced epoxy technologies to achieve high compressive strength, high impact resistance and low shrinkage.
Due to the low odour, low VOC formu-lation maintenance crews can work faster and with fewer breaks, reducing downtime and increasing productivity. Also due to the increased compressive strength, higher operating temperature, and high impact resistance, PC 9020 will likely last longer in service and require less frequent servicing of crusher cone surfaces.
Henkel has truly listened to its custom-ers and delivered a unique product that truly helps increase profitability in the resource mining sector. Loctite Nordbak PC9020 is available in 2 and 5 gallon pail sizes with participating distributors. NMT

Today’s tumultuous, cyclic industry has challenged mining companies to max-imize productivity and make process-
es safer, cleaner and more efficient. A 2010 survey of mining executives
commissioned by Mincom asked respon-dents to identify their current challenges by level of urgency. It may not come as a surprise that ‘ensuring workplace safety’ topped the list with 71 per cent of respon-dents identifying it as a top priority. Also high on the list were ‘improving perfor-mance and operational effectiveness’ (67 per cent) and ‘addressing environmental concerns’ (37 per cent).
It’s clear that conservation and produc-tivity are issues everyone in the mining industry faces. How can we make opera-tions safer, cleaner – and spend less time and money? Often we see these issues as mutually exclusive.
Investing in technology that meets both needsSandvik Mining is developing mining equipment that meets the top safety and efficiency standards, and is investing in technology that can be retrofitted to older equipment to improve its operation. For instance, the Sandvik Compressor Management System (CMS) provides a solution to the inherent inefficiencies of rotary blasthole drills that have a direct connection between the engine and com-
pressor. The system isolates the compres-sor and eliminates the need to maintain pressure when the machine is not drilling. This reduces the load on the engine, sav-ing a significant amount of fuel and reducing wear and tear.
Here’s how it works:• START-UP: Holds the inlet butterfly closed to
allow the engine to crank, start and acceler-
ate to low idle
• OFF-LOAD: Regulates receiver pressure and
evacuates the main compressor
• ON-LOAD: Throttles the volume of the
compressor
• SHUT-DOWN: Unloads the compressor from the engine to allow for cooler engine shutdown
This patented solution can be installed on new or existing Sandvik rotary drills and has been proven to reduce fuel con-sumption by 20-35 per cent, extend the life of the engine and compressor and lower emissions. Sandvik Mining first tested the CMS at the Drayton Coal Mine in Hunter Valley, Australia. The system, retrofitted to a DR460 rotary drill, produced a whopping 33 per cent fuel savings. The CMS nearly doubled the engine’s life by easing the wear and tear. Following this trial, the Sandvik Mining team set out to duplicate these results with Cloud Peak Energy.
The right partnershipCloud Peak Energy is headquartered in Wyoming and is one of the largest coal producers in the United States, supplying the country with about 4 per cent of its sustainable electricity. The company oper-ates three surface coal mines in the Powder River Basin (PRB) and is the only pure-play PRB company – meaning it is the only company that mines exclusively in the PRB. As one of the safest coal producers in the

United States, Cloud Peak Energy special-izes in the production of low sulfur, subbi-tuminous coal. The company is comprised of properties acquired from several other companies throughout the years, and it is recognized for its exemplary performance in its safety and environmental programs. So, when Sandvik Mining was looking for a new partner to prove its CMS technology in the United States, Cloud Peak Energy was an obvious and ideal choice.
InstallationWhen the trial was proposed, Cloud Peak Energy was interested in the benefits but questioned if the system could actually save 25-30 percent of fuel savings. Sandvik Mining representatives were confident the CMS would deliver, and they knew Cloud Peak was the right partner to prove this product, so they took an unconventional approach – they offered Cloud Peak Energy a one-time guarantee. Before installation,
the terms were set – if the system delivered 90 percent of projected savings, Cloud Peak Energy would purchase the CMS at full price. If it underperformed, Sandvik Mining would remove the system at no cost.
Cloud Peak Energy chose to have the Sandvik CMS retrofitted onto a 14-year-old rotary drill at its Cordero Rojo coal mine in Gillette, Wyoming. The companies chose this machine because it has been in full production for years, providing a solid reference point for the historic fuel con-sumption. And though the rig is approach-ing 60,000 hours, Cloud Peak Energy expects to keep the machine in production for years to come, giving time to track the progress of the CMS over time.
Sandvik Mining estimated that the CMS would save 23 per cent of fuel. Once the system was installed and calibrated, Sandvik Mining technicians used the Engine Control Module (ECM) data as a reference point.
Exceeding expectationsBefore the installation, the drill was using 22.9 gallons of fuel per hour. After run-ning the Sandvik CMS for five weeks, the rig was only using 16.9 gallons per hour – a reduction of 26.2 per cent. This cut translates to savings of approximately 24,000 gallons of fuel*, $108,000* and more than 300 tonnes of carbon emis-sions* annually – on fuel alone. With the Sandvik CMS, Cloud Peak Energy will save thousands of dollars on fuel every year. Additional savings are expected from increasing the engine life.
The Cloud Peak Energy drill operator cited that the most significant difference in fuel savings could be seen when he was changing out steels or tramming to a new hole location. There was also a noticeable difference in how the CMS helped start the machine in cold weather – conditions which operators at the Wyoming location are no strangers to. Pleased with the trial results, Cloud Peak Energy purchased two new Sandvik drill rigs for 2013 with Sandvik CMS installed. NMT

In subterranean mining operations, access to communication networks deep underground is critical for trans-
porting data, voice, and video, and other supporting applications that are essential for efficient and safe operations.
Whether accessing sophisticated ERP or Maintenance Management Systems, engaging in fleet management, video sur-veillance, or access control, or protecting miners with wireless locator systems, these networks serve as a literal lifeline between workers deep within mines and surface operations.
For this, mining networks require more than permanently installed network cabling, it also requires unique deployable systems designed for quick installation, extension and even relocation as the active mine site area moves, or equipment is moved in and out.
Ruggedized Fiber Optic SystemsGiven the increasing bandwidth require-ments and concerns about electromag-netic interference (EMI), fiber optic cable is quickly replacing the more tradi-tional choice, copper. Designed to sur-vive the rigors of a mining environment, this extremely ruggedized cabling can withstand everything from dust and
debris to chemical exposure, tempera-ture extremes, radiation, electrical power transients, interference, fire, moisture, humidity, water, crush, tension, flexing, impact, and vibration.
The fiber optic cable, however, is only a component of a complete, deployable sys-tem, explains Rick Hobbs, Director of Business Development at Optical Cable Corporation (OCC). OCC is a company that designs and manufactures fiber optic cabling, connectors and assemblies for harsh environments such as mining.
According to Hobbs, other key ele-ments include hardened cable jacketing; “genderless” connectors for quick deploy-ment without regard for male or female ends; and hybrid options that include cop-per along with fiber to provide power for underground Wi-Fi networks.
Hardened CablingFor locations that require compliance with MSHA’s Part 7, Subpart K of Title 30 of the Code of Federal Regulations (CFR) signal cables mining applications, OCC typically recommends its MSHA-rated B-Series Breakout Cable.
MSHA cables are designed to withstand the rigors of difficult pulls, high tensile loading and severe crush occurrences and

can repeatedly endure the abuse associated with the extreme demands in surface and sub-surface mining.
The B-Series Breakout Cable is one of OCC’s most rugged, high strength cables. Each individual, color-coded sub-cable has its own tight-buffered coating to pro-tect each fiber.
In addition, these cables have a tight-bound outer jacket, which is pressure extruded directly over the cable’s core. This combination of a helically stranded core, and a pressure extruded outer jacket provides an overall cable construction that offers crush and impact protection and increased tensile strength.
“The Breakout Cable is essentially a double-jacketed construction,” says Hobbs. “Instead of 900 micron buffers and an outer jacket, each of the 900 micron buffers has a 2.5 millimeter sub-unit protecting it.”
As an alternative, if cost is an issue and the conditions warrant it, MSHA-rated distribution style cabling is an alternative. This cable is also extremely rugged, fea-turing the helically stranded core and extruded outer jacket, but not the addi-tional 2.5mm sub-cable for each fiber.
According to Hobbs, other MSHA-rated cable designs are available, offering escalating degrees of cable protection to meet the specific needs of an application.
These include alternative jacket mate-rials, such as PVC and polyurethane, which are specifically tailored to meet the mechanical and environmental needs of the application. Additional options within each cable type include jacket materials for applications requiring lower coeffi-cient of friction, chemical resistance, and temperature flexibility for both low and high extremes. Water tolerant options are also available that take advantage of the qualities of tight buffered cable and super absorbent polymer aramid yarn.
Hybrid Cables, ConnectorsFor applications that can benefit from fiber optics and copper, hybrid cables offer both within the same cabling sheath.
A distinct advantage of a hybrid cable-connector solution is that the customer can bundle both the high performance of fiber with the copper power or control signal in one cable. This reduces the num-ber of cables that must be designed, pur-chased and deployed into a system.
Hybrid cabling also facilitates installa-tion of wireless access points underground.
Unlike traditional wireless networking devices that require 110-Volt AC power for each device, with a hybrid system 12vdc or 48vdc power can be supplied in the same cable to power wireless routers, as well as other electronic devices.
As a result, certified devices are able to communicate throughout the network, including devices such as VOIP devices and IP Cameras.
This provides personnel, even deep within mines, with the means to commu-nicate with each other and even make calls outside the mine.
Wireless systems also play a key role in providing post-accident miner locator tracking and two-way communications, a requirement of the Mine Improvement and New Emergency Response Act of 2006.
Some of the available tracking systems involve small, wearable radio frequency identification (RFID) locator tags that can be attached to miners or a piece of equip-ment. These tags communicate with wire-less access points or nodes placed in stra-tegic locations throughout the mine to pinpoint their location.
Genderless Connectors“Genderless” connectors, designed for quick deployment, are able to connect with one another allowing the user to connect fiber optic cables without regard for male of female ends.
Companies such as OCC have further simplified the genderless design with user friendly mating interfaces (the company’s EZ-Mate family) capable of “blind mate” and/or applications that require thou-sands of mating cycles.
The connector system is designed to resist extreme harsh mechanical and envi-ronmental conditions including high vibration, mechanical and thermal shock, and fluid immersion.
With genderless connectors, multiple identical cable assemblies can be daisy-chained together over a distance of up to several kilometers while maintaining polarity. Polarity can be an issue when connecting an odd number of traditional male to female gender connectors. In such cases, additional connectors, which add signal loss, are required to correct polarity.
In high traffic areas where the risk of damage to installed cabling is elevated, spare assemblies, fitted with genderless connectors, can be stored to allow for fast and easy replacement with minimal inter-ruption to operations.
Increasing Conversion to Fiber OpticsAccording to Hobbs, there are many min-ing companies that are converting to fiber optics as the costs for components con-tinue to drop, making fiber a better solu-tion than copper in most applications. Even die-hard copper devotees are mov-ing to fiber and when they do, they rarely look back.
“When System Engineers realize the increased bandwidth opportunities afford-ed by installing a fiber network, they usu-ally expand their requirements, and iden-tify creative new ways to utilize the tech-nology to provide innovative solutions for their applications,” says Hobbs. NMT

Paints and Coatings can help owners protect equipment and save moneyBy John Reiser*
The production processes that are developed in the mining and minerals industry are manufactured to be exposed in very aggressive environments. Chemical and abrasion on struc-
tures and equipment, regardless if they’re made of steel or con-crete, are subject to significant deterioration. This causes damage and added high cost to the operation that can be reflected in the destruction of equipment and structures in the arrest of the pro-duction process which becomes very costly. Also potential per-sonal misfortunes with accidents, which would require large sums of compensation for an employee, thus directly harming the image of the mining operation and company.
Manufacturers of paints and coatings worldwide that have major centres for Research and Development (R & D Labs) dis-tributed globally in its international subsidiaries have developed high-tech products for durable protection from the elements, structures and equipment used in the mining industry. The differ-ence between these paintings and coatings and what we normally know as conventional paints (e.g. those called domestic or decora-tive or those for light duty purposes, etc.), is its chemical composi-tion, structured around polymeric components, highly resistant chemical and physical properties in extreme conditions to which they are exposed. With this, and only this, we see longer life of components, equipment and structures used in the production processes of the mining industry.

Today, in addition to the important features described in the previous paragraph, some of the paints and coatings dedicated to this highly modernized process, have invested large sums of money in developing new products that add operational ele-ments to the painting process. These coatings provide added value and significant performance to a company’s mining opera-tions and that we can describe in three fundamental concepts:
1 Paint 100% solids, which are paints or coatings whose composi-tion does not contain volatile solvents, which allows utilization of the total contents of the container and application of the thick-nesses required in fewer layers (hands), thereby saving time and cost of labour in the process of painting or coating equipment for a mining facility structure. In addition to this, there is clearly a quantitative reduction in the emission of pollutants (organic solvent) to the environment, which makes these materials con-sidered ecologically desirable. Many new paints or coatings are now manufactured with “HAPS” Free Solvents, (Hazardous Air Polluting Solvents). Also non-photo chemically reactive coatings are becoming more desirable as well with increasing restrictions on coatings throughout North America.
2 Paints and coatings which are fast drying allows expedited handling of pieces in the painting process with less time,
thereby reducing the retention periods of these components in steel fabrication facilities. Components which are manu-factured as well as in the maintenance processes provide a significant decrease in time that equipment and structures will become un-operational in the mining operation. This reduction in detention time thereby reduces process costs.
3 Rapid Return to Service (RRS), this concept, complements the previous two mentioned and allows equipment or painted structures operational in a very short period of time. This concept compared to traditional paints will obviously provide a benefit to the mining and minerals process.
As you can see, Industrial Paints and Coatings have placed focus in the mining and minerals processes. Developing prod-ucts with new technologies is an extremely important activity. These new technologies are working to provide the client an exceptional paint/coating for their special processes, which enables the mining and minerals industry to continue working with minimal shut down time and without suffering damage to their facilities or expensive costs and increases profits.
