Fourth Annual International Mining Health & Safety Symposium

1. Fourth Annual International Mining Health & Safety Symposium MSHA Communications and Tracking Update Approval and Certification Center April 8, 2011

2. Communication and Tracking (CT) Installation Update • 192 Complete Installations representing 36% of mines • Approved ERPs specify: • Wireless Node-Based Communications – 22% • Wired Node-Based Communications – 29% • Leaky Feeder Communications – 50%

3. MSHA Communication and Tracking Activity • Since January 2006, A&CC has issued: • 186 new or revised approvals for communication and/or tracking systems. • 67 new • 119 revised • Currently evaluating additional 53 applications, including: • Wireless mesh • Through-the-earth technology

4. Other Recent Communication and Tracking Activity • Working section installations being deployed successfully • Wired system manufacturers pursuing wireless options • Leaky feeder manufacturers are exploring adding wireless access points (nodes) • Wired mesh manufacturers are investigating wireless options • Text messaging only systems are pursuing voice options

5. Other Recent Communication and Tracking Activity • Some CT manufacturers are adding capabilities for: • Gas monitoring • Continuous dust monitoring • Collision warning

6. MINER Act Refresher • Post accident communication must be provided between underground and surface personnel via a wireless two-way medium. • An electronic tracking system must be provided that permits surface personnel to determine the location of any persons trapped underground. • ERPs shall be reviewed periodically but at least every 6 months to consider: • All comments submitted by miners or their representatives • Intervening advancements in science and technology that could be implemented to enhance miners ability to evacuate or otherwise survive an emergency

7. MSHA 6 Month ERP Reviews • Ensure system will be completely installed by June 15, 2011 • Review to ensure adequate survivability • Check recent technology advancements; mine operator should seek to constantly improve system capabilities

8. Fourth Annual International Mining Health & Safety Symposium MSHA Proximity Detection Update Approval and Certification Center April 8, 2011

9. Fatal Accident Data Study – 1984-2010 Study identified crushing fatalities that could have been prevented by proximity detection: 70 total in CMSH 30 continuous miners 25 shuttle cars or coal haulers 10 scoops 5 mobile bridge conveyors 5 total in MNM

10. Remote Control Continuous Mining Machine Fatalities 34 since 1984 29 victims had possession of remote control 6 maintenance

11. MSHA Approved Proximity Detection Systems Nautilus International Coal Buddy System Strata Safety Products HazardAvert™ System Joy/Matrix Design Group M3-1000 System

12. Nautilus International “Coal Buddy System” Three current installations ICG Sentinel Massey (Independence Coal) Cook and Randolph Mines One system ordered for Patriot’s Federal #2 Mine Massey Energy ordered 30 systems

13. Strata Safety Products HazardAvert™ System Experience with installations at: Consol Jones Fork Mine ICG Viper Mine Peabody Black Beauty Mine Consol Buchanan Mine Current focus in South Africa where there are currently eight (8) complete u/g coal mine sections using HazardAvert™ Currently testing system at Consol Buchanan Mine and Peabody Willow Lake Mine

14. Joy/Matrix Design Group “Miner Monitor M3-1000” MSHA approved in February 2009 19 total systems installed. Most are at Alliance Coal Company Mines, including : Riverview Pattiki Dottiki Mettiki Tunnel Ridge Also at James River Coal’s Leeco #68 Mine

15. Joy/Matrix Design Group “Miner Monitor M3-1000” Zone Types Warning Zone, further away from the machine, provides operator feedback through a series of yellow LED lights mounted on each receiver Shutdown Zone, closer to the machine, provides operator feedback through red LED lights and disables certain functions such as tram and conveyor swing Operational Modes Tram Mode defines a larger, full machine zone accounting for increased machine speed Cutting Mode defines a smaller, partial machine zone near the bumper accounting for operator positioning away from haulage interaction

16. MSHA, NIOSH, WV MSTTF Visit to South Africa Observed: Strata Safety Products Tramguard™ at Sasol Twistdraii Underground Coal Mine SafeMine GPS System at Anglo New Vaal Colliery Surface Coal Mine Becker CAS System at Xstrata Kroondal Underground Chromium Mine Booyco CWS at Anglo Greenside Colliery underground coal mine

17. South Africa PDS Experience Sasol uses on all face equipment including: Continuous mining machines Shuttle cars LHDs (scoops) Roof Bolters Feeder Breakers Anglo Coal uses on all face equipment except CMs

18. Surface Collision Warning Systems • SafeMine GPS • AMT RFID and Video System • Preco Radar System • Becker CAS System • Acumine ACASS System • Strata HazardAvert™

19. MSHA Rulemaking Activity Published RFI January 31, 2010 14 Responses received Available at www.msha.gov Working on Emergency Temporary Standard
