  1. ERP Implementation Issues Moderator: Panel: Dave Chirdon, Tech Support Larry Cook, District 4 Don Foster, District 2 Juliette Hill, Tech Support

  2. ERP Issues: Additional Coverage Areas • Coverage in belt entries • Coverage in returns • Coverage on longwalls • 200’ accuracy on face • C&T in the tailgate entry – whether it is the secondary escapeway or a strategic area

  3. ERP Issues: Strategic Areas • Defining strategic areas • tailgates of longwall sections that are NOT secondary escapeways, etc. • tracking accuracy • extent of communications coverage • escape capsules, etc.

  4. ERP Issues: Survivability • Hardening in front of seals • Adequate redundancy

  5. ERP Issues: Performance • Text vs. Voice • Adequate coverage • Low coal performance • Backup battery capacity • Tracking tag read by multiple readers • Dependent upon the operation of the system • Tracking system may require periodic calibration to maintain tracking accuracy

  6. ERP Issues: Interference • RFI (minimum separation distances) • EMI • Remote Control • Defining known sources of interference in the ERP (i.e., CO monitoring systems, remote control units, etc.) • Administrative procedures or engineering controls

  7. ERP Issues: Maintenance • System failures and backup plans: • defined intervals for check ins • established procedures for missed checks • Maintaining backup systems in required coverage areas

  8. ERP Issues: Emergencies • Procedures for emergencies • Emergency communications channel • Communications intervals • Cycling the use of hand held units (i.e., for extending battery life)

  9. ERP Issues: RAs • Technical and enforcement issues of two way communication through a refuge chamber (75.1600-3) • Modifying chambers • Maintaining hardwired phones • Inspecting comms inside the RA

  10. ERP Issues: Expanding Uses • Remote monitoring of C&T systems (remote communications centers) • Mine rescue activities - how exploration may change with communications technologies

  11. Q&A Session
