A Redpine Mining Portfolio Solution

Assure - Minesafety™

Mines are hazardous work environments. A prime concern is the safe evacuation of miners trapped in a mine or portions of a mine due to rockfall, flood, explosions, or fire. Rescue teams should be aware of the number of miners, the identity of each miner working underground, and the last known location of each one of them. Another area of concern is worker injury due to proximity to operational vehicles and heavy equipment. Miners need to be provided signage and warnings about areas that are unsafe for entry and when they need to move to a safe zone. Vehicle operators need to ensure safety when in the vicinity of other vehicles that may not be directly visible. Supervisors at mines should also be immediately alerted when unauthorized personnel move into hazardous or sensitive areas.

The use of technology in mines is highly important to improve productivity and operational efficiency. This involves knowledge of the real-time location of people and equipment as well as analysis of movement over a period of time. Mine management personnel should be aware of equipment utilization rates to determine an optimal allocation of resources for activities in different areas of the mine.

Requirements and Challenges

The Assure Minesafety™ solution addresses all of these requirements and challenges, and more. It combines innovative hardware components built with the company’s own industry-leading wireless MCUs and a comprehensive software platform that provides location visualization, analytics, alerts, and more.

Solution Overview:

The solution provides the current, and last known location of personnel. It provides filters to categorize personnel in specific zones. The information is displayed as a list or on a map on a desktop or mobile device for ease of use by supervisors or rescue teams. The visualization also replaces the legacy ‘tag board’ on which miners place their name tags before proceeding underground.

Real-Time Personnel Location

Some areas in the mine may be restricted to certain personnel categories only, while other areas may be closed for a specific duration due to hazardous operations in progress. Mines often have signages as visual indication to personnel. However, safety requires positive identification of unauthorized entry. The Assure Minesafetysolution provides for such dynamic definition of zones and providing instant alerts when personnel move into such zones. Miners are also notified which helps them take immediate action.

One of the components of Assure Minesafety™ is a Wi-Fi enabled cap lamp. When a miner needs to be informed of a general emergency, or a specific situation, the solution provides for the ability to send messages to his cap lamp. These messages result in the blinking of the lamp which the miners can notice even in noisy environments. The solution also provides for acknowledging receipt of the warning by pressing a button on the miner’s cap lamp. Safety staff then receive notification of the miners who have acknowledged the warning.

Miner Notification

Assure Minesafety™ provides for the determination of excessive proximity of two vehicles, or a vehicle to a miner, and provides warnings to personnel involved in the situation. Supervisors also are informed of the instances of these proximity situations which help them review their operational procedures.

Proximity Notifications

A lone miner, caught in an emergency situation, can press the button on his device to have an instant notification sent to a supervisor or safety staff wherever they may be. The system also detects lack of movement of a miner and notifies safety staff for further action.

NO ENTRY

The Assure Minesafety™ solution integrates several components to offer new levels of safety and operational efficiency. These include tags, wireless infrastructure elements, and application software. Tags come in multiple form factors - asset, badge, cap lamp, and vehicle mounted. The wireless infrastructure used is the Cisco CMX solution with which all other components are compatible. For augmenting the infrastructure and for precise determination of movement of personnel or equipment past a specific entry/exit point, the solution includes a Chokepoint Exciter. The software application provides location based visualization, reporting and management of assets and personnel, and all the features of the solution described above. The software provides an easy web based access from any type of device - desktop or mobile.

How It’s Done

Assure Minesafety™ analytics included in the solution operates on current as well as historical data. Mine operations staff will therefore be aware, for example, of the path taken by an equipment or miner over a specified period of time. They are informed of the concentration of personnel in specific areas and the utilization rate of equipment.

WM7 Personnel Tag

The WM7 tag has an employee ID badge form factor which is suitable for tracking personnel with multiple features such as motion detection, multi-colored LEDs, and two-way communication options. The WM7 contains a rechargeable battery.

WM6 Asset Tag

The WM6 tag is suitable for tracking a variety of devices and equipment using multiple attachments such as tamper sensing, motion detection, and multi-colored LEDs. It contains user replaceable batteries that can last up to three years, depending on operating conditions.

WM11-B/V Vehicle Tag

The Vehicle tag can be housed in a moving or stationery vehicle used in mines and is a part of Redpine’s RTLS system offering. It is a locating device that enables the tracking of the location of an asset or a person or a vehicle based on active Wi-Fi technology. The tags are powered using vehicle battery.

Chokepoint Exciters

The WM-CPE Chokepoint Exciter is a fully Wi-Fi compliant device that wakes up RTLS tags and registers their presence. It uses Wi-Fi packets to wake up WiseMote™ tags in the vicinity, collects information on them, and forwards the information to a designated server.

Intelligent Cap Lamp

Redpine WiseMote™ tags come in multiple form factors. All tags support both 2.4 GHz and 5 GHz Wi-Fi bands. The tags also provide information to the system about specific parameters such as battery life, emergency button press, motion detection, chokepoint excitation, and other events.

Redpine Solution Overview: Assure Minesafety™, a Redpine Mining Portfolio Solution

These cap lamps have been created specifically for use by personnel in underground mines. The lamp is fitted with a Wi-Fi tag that sources its power from the lamp’s rechargeable battery. The lamp’s push button is used as the emergency button. The device supports two-way communication. For e.g., miners can be notified of an emergency via an incoming message on the Wi-Fi device along with a feature that flashes the lamp to alert the miner of the incoming notification.
