  2. Methane Ignition and Coal Dust Explosion in Mine Entry

  3. Mine-Wide Two-Way Radio Communications Mine-wide two-way Radio Communications are required during the first few minutes of an incident or the situation goes out of control. • 1984 Welburg Mine Fire • 27 dead • Only a 900-ft walk to safety • 2002 Quecreek Water Inundation • 9 trapped • 2004 Sago Mine Explosion • 12 dead • Only an 1,800-ft walk to safety

  4. Radio Communications and Tracking System Features • Wireless two-way transmission • Natural waveguides • Through-the-earth waveguide (ultra-low frequency) • Conveyor belt/cable waveguide (low frequency) • Coal seam waveguide (low frequency) • Passageway waveguide (ultra-high frequency) • Intrinsically safe • Operational when ventilation is disrupted

  5. Radio Communications and Tracking System Features • Three redundant tracking and location subsystems • Real-time network with graphic display • Surface Delta Tracker to pinpoint location • In-mine Fox Hunter Antenna • Extremely reliable network • F1/F1 repeater drilled into roof rock • Expandable and self-healing • Through-the-earth redundancy • Modulated for digital transmission

  6. Radio Communications and Tracking System Features • Cap lamp-powered tracking beacon • Cap lamp transceiver • Multi-mode • Two-way text messaging • Synthetic voice capability • Bluetooth link to monitor physiological condition and provide PDA download

  7. Radio Communications andTracking System

  8. Tracking BeaconThrough-the-Earth Waveguide

  9. Tracking Beacon • MSHA IS Certification Investigation IA-22294 • Keypad • OLED • Micro controller • Class L Transmitter

  10. Delta Tracker • Suppresses surface radio frequency interference (RFI) • Detects spreading EM waves • Pinpoints trapped miners’ location • Determines depth

  11. Delta Tracker Detectionof Mine Voids

  12. Suggested Regulation Changes • Combine 30 CFR 75:1600 and 30 CFR 49 • Require the same network and equipment • Require 96-hour system operation when ventilation system is disrupted

  13. Offer Tax Incentives • Purchase of equipment • Installation of equipment • Maintenance of equipment • Training of maintenance personnel
