  4. People • Labor shortage • Two – twelve hours shifts / day • Operate 4 – 6 days per week • Maintenance 1 day per week • Geographic locations change often • Exposed to nature’s elements • Perceived as a short term job

  5. Reserves • Seam heights 2.5 – 28 ft • Sustain a 1-3 year project • 40,000 – 200,000 tpm • Best if not previously auger mined • Competent roof or ability to leave head coal • Mine bottom up

  6. Equipment Spread • Modified Continuous Miner • Cascading Conveyor Cars • Launch Vehicle • Stacker - 54 inch belt • Bulldozer - pushing coal • 2 Endloaders – loading & unloading cars & loading trucks • Water Storage Tank

  7. Communication • Real time info in the cab • Web based storage • Real time communication with home office (under development)

  8. Management Skills • Long term mine planning • Synchronization of equipment • Synchronization of qualities/ markets • Keeping available wall

  9. Longwall/Highwall Similarities • Sole purpose is to cut coal • Initial reluctance to rely on the technology • Typically the lowest cost coal from a mining complex • Keeping gate roads ahead is as challenging as keeping wall available

  10. Safety Mining Method NFDL Rate ADDCAR 0.00 Surface Mining 1.48 Underground Mining 5.15 3rd Qt – YTD 2005

  11. Productivity Mining MethodTPEH Western Surface Mines 22.8 ADDCAR 18.5 Longwall Mines 5.1 Eastern Surface Mines 4.3 Non-Longwall Underground Mines 3.5 3rd Qt – YTD 2005

  12. Narrow Pit System • Footprint reduced from 90 – 45 ft • Continuous coal flow • Fewer fines • Horizontal & vertical guidance • 1,200 ft penetration • Purchase – lease – contract mine

  13. Conclusion If you keep wall …. you experience this
