Mine Signal, Warning and Communication System.

  1. 1. Roof fallLimited space Water flow Complicity Darkness Gas outburst Thermal complicity
  2. 2.  Stench gas Audible or visual alarms Pager phone Telephones and Messengers
  3. 3. (500BC) Visual signals (19th Century) Audio signals (Present)Advanced electrical/electronic signal
  4. 4.  Bucket positioning in shaft To keep working steps cyclic Surviving from accident To protect roof fall To protect mine fire For safe shunting work For repairing and conservation of road For Locomotive routing signal
  5. 5.  Cage shaft Skip shaft Mine car Rail track signal (changing) Conveyor belt signal Fire signal and Shield movement signal
  6. 6. General types of signalCommon signal Emergency signal
  7. 7. Types of Technical signal According According toAccording to to According to Their function their specific operation location process
  8. 8.  Shaft signaling Train signal Mine fire signal Roof movement signal Signal interconnection Two way communication
