erp issues additional coverage areas
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
erp issues strategic areas
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.
erp issues survivability
ERP Issues: Survivability
  • Hardening in front of seals
  • Adequate redundancy
erp issues performance
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
erp issues interference
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
erp issues maintenance
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
erp issues emergencies
ERP Issues: Emergencies
  • Procedures for emergencies
    • Emergency communications channel
    • Communications intervals
    • Cycling the use of hand held units (i.e., for extending battery life)
erp issues ras
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
erp issues expanding uses
ERP Issues: Expanding Uses
  • Remote monitoring of C&T systems (remote communications centers)
  • Mine rescue activities - how exploration may change with communications technologies
