ARDVARC CONCEPT

1. Create an Automated drill system that would allow the mine operator to train new personnel in a very short time and make them 80-95% as effective as their best operators.

2. Create an Automated drill system that would allow machine operation in hazardous environments that would normally prevent personnel from entering.

3. Create an Automated drill system than reduces the human variance in the drilling process.

4. Create an Automated drill system that could be deployed on EVERY make/model of drill produced.

5. Create an Automated drill system that utilized off the shelf hardware for worldwide parts support.

6. Create an Automated drill system that learns as we learn.7. Create an Automated drill system that tells us what is wrong and how to fix it.8. Create an Automated drill system that monitors KPI’s and reports them at nearly

live intervals9. Create an Automated drill system that can be monitored LIVE via internet

ARDVARC™

Advanced Rotary Drill Vector Automated Radio Control

The first step to our Power Performance Drill package is upgrading the drives to give you unparalleled speed control.

The second step is to upgrade to our Industry Proven ARDVARC system. With several cumulative modules to build upon, you can start small and add functionality as you require.


TorqReg™ Power Performance Drill Upgrades

• Replaced older drives with new off the shelf Siemens Digital DC Drives utilizing torque regulation for optimum speed control in the Hoist and Pulldown modes.

• Achieves a level of control that was not avaiable with older systems.

• While the machine is in the Hoist mode - be it low hoist or hight hoist - the drive acts as a Speed Control System.

• When the machine is placed in the Pulldown mode, the drive then switches to a Torque Control System where the operator selects how much torque - or down pressure - he wishes to apply.

• Implemented in cumulative stages or all at once:

– Level 1 - One-Touch Drill Control– Level 2 - Data Collection Server– Level 3 - GPS-Locator– Total - Auto-Propel Semi-Autonomous Control

• All of our ARDVARC modules use off the shelf hardware and a “no black box” philosophy. – This keeps the system open to allow the

implementation of 3rd party enhancements in the future.



• ARDVARC systems are simple enough to allow an operator with minimal training to use the system.

• ARDVARC makes the machine “smart” with respect to ground conditions when drilling.

• Operator only needs to propel the machine from hole to hole.

• More consistent holes – depth and time to drill.• Better control of machine drilling characteristics.• Maintenance gains due to consistent control of

the machine.• Less training required to get an operator as

proficient as your best operator.– The ARDVARC system is repeatable over and over again.– 100% focus on the drill operation through automation for

machine consistency

Level 1 - One-Touch Drill Control

MACHINE HEALTH

Active Machine Status screen changes colors from green to yellow to red on all key machine systems to indicate status of each system. Green indicates no problems, yellow indicates warnings are present and red indicates an active system fault.


MACHINE HEALTH

Active fault screen displays help text when

needed on active faults to assist in troubleshooting


MACHINE HEALTH

Machine fault history displays the same help text, simply

touch the fault and read the

text!


MACHINE HEALTH

Smart machine help text assists

operators and maintenance

personnel with machine

operations.


• Data is collected in a SQL Server Database• Data is transmitted via a wireless Ethernet

network to a central data server.• Data collected:

– Hole Data – recorded at one foot intervals during the cycle– Hole-by-Hole Data – recorded at the end of each drill cycle– Shift Data – recorded at the end of each shift

• Drill statistics by machine and by operator kept on a central server. (Operator and machine KPI)

• Remote monitoring of operator screens.

Level 2 - Data Collection Server

Level 2 - Data Collection Server – Hole Data


Presenter

Presentation Notes

The screen shots are viewed with Access but the data comes from SQL


Level 2 - Data Collection Server – Hole-by-Hole Data



Level 2 - Data Collection Server – Hole-by-Hole Data (cont.)



Level 2 - Data Collection Server – Shift Data



• Eliminates manual marking of holes.• Uses a mine duty network for high

precision GPS location.• Drill Hole patterns are downloaded to

the drill from the remote office server via the wireless Ethernet network.– Engineers develop drill patterns in

AutoCAD and download them as mine coordinates directly into the drill(s).

Level 3 - GPS-Locator



• Operators manually propel to the location and the hole target shows on their Operator Interface.– The One-Touch button

is used to drill automatically once there.




• With GPS coordinates downloaded, the operator simply selects the hole drilling sequence and pushes one button to start the cycle.

• The machine automatically propels itself to the next hole, targets the hole with great accuracy, levels, waters, collars, drills, raises the bit and jacks and readies itself for the next move.

• The operator again pushes one button to give permission to the machine to automatically start the cycle again. (for safety)

Total Solution- Auto-Propel Semi-Autonomous Control





Operator chooses targeting

sequence for holes

Zoom in to change the scale




Operator interface shows the sequence of holes as they are

being drilled

One Button for permission to

move as a safety precaution




With the drill in propel, the

system shows the operator the

target

Location of the machine is always

updated




As the target nears, the system zooms in to show the operator the

hole number

Remember, all the operator is doing is monitoring, all this

is happening

AUTOMATICALLY!




The target is achieved and

now the machine will drill the hole

automatically

When completed, the system will ask for permission to advance to the

next hole


VARIANCE REDUCTION

1. AUTO DRILL FEATURE ENSURES CLEAN, HIGH QUALITY HOLE IN 90% OF DRILLING CONDITIONS.

2. DRILL TO AN END OF HOLE ELEVATION INSTEAD OF AN END OF HOLE DEPTH!!!

3. AUTO LEVEL FEATURE ENSURES BOTTOM OF HOLE COORDINATES ACCURATE TO WITHIN 10 INCHES OF TOP OF HOLE COORDINATES.

4. AUTO DRILL SYSTEM MONITORS EVERY SIGNAL ON THE MACHINE AT 4 MS INTERVALS TO KEEP THE MACHINE OPERATING AT OPTIMAL SETPOINTS.

TRAINING REDUCTION

OPERATOR NEEDS TO KNOW HOW TO MOVE THE DRILL FROM HOLE TO HOLE, THEN PUSH THE ONE TOUCH DRILL CONTROL START BUTTON………………OR:


TRAINING REDUCTION

……………….GO WITH THE FULLY AUTOMATED VERSION OF ARDVARC AND TEACH YOUR OPERATORS TO PROGRAM IN THE PATTERN.

OPERATORS ARE USING THE AUTOMATED DRILL FEATURES OVER 85% OF THE TIME INSTEAD OF USING THE MANUAL

CONTROLS.


TRAINING REDUCTION

HOW DOES THIS EFFECT THE DRILLING PROCESS?1.END OF HOLE ELEVATION IS ACCURATE TO WITHIN THE RESOLUTION OF THE HEAD POSITION DEVICE.

1. BE MACHINES ARE +/- 3 INCHES2. IR/ATLAS COPCO MACHINES ARE +/-.01 INCHES

MACHINE LEVEL ACCUARACY TO WITHIN .25 DEGREES IN LESS THAN 45 SECONDS WHICH EQUALS LESS THAN A 6 INCH ERROR AT THE BOTTOM OF A 50 FOOT HOLE.


Autonomous Enabled ???

• What is Autonomous??- Remote control – someone driving a drill from another

location.

-Full Autonomy – Drills and entire pattern on the bench and can drive to the maintenance shed if needed.

-Something in between?


Other Considerations

• It is more that just a control system, it is a mine methodology

- How will you control the bench?

- How do you do collision avoidance?

- Is your maintenance program adequate? You can’t have failed sensors temporarily

bypassed.


SAFETY ASPECTS

•Because of Automated Features, personnel can be placed in a safe location

•More than one machine can be monitored via wireless Ethernet by only one person

•Machines can be operated in Manual Mode remotely using any Ethernet radio

•Machines constantly monitor forces on the mechanical components to keep the machine running within manufacturing specifications
