ERP Issues: Additional Coverage Areas

Coverage in belt entriesCoverage in returnsCoverage 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

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

Hardening in front of sealsAdequate redundancy

ERP Issues: Performance

Text vs. Voice Adequate coverageLow coal performanceBackup battery capacityTracking 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

RFI (minimum separation distances)EMIRemote ControlDefining known sources of interference in the

ERP (i.e., CO monitoring systems, remote control units, etc.)

Administrative procedures or engineering controls

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

Procedures for emergencies Emergency communications channel Communications intervals Cycling the use of hand held units (i.e., for

extending battery life)

ERP Issues: RAs

Technical and enforcement issues of two way communication through a refuge chamber (75.1600-3)

Modifying chambersMaintaining hardwired phonesInspecting comms inside the RA

ERP Issues: Expanding Uses

Remote monitoring of C&T systems (remote communications centers)

Mine rescue activities - how exploration may change with communications technologies
