Gas Monitoring System

The gas monitoring systems widely used in Australian underground mines are:

Advantages of Tube Bundel System

Disadvantages of Tube Bundel system

  • Continious monitoring

  • Monitoring of full range of gases

  • Sometimes difficult to locate damage which cause leakage and oxygen to enter system

  • Requires frequent auditing of system

  • Can have time delay in gas readings as the tubes become longer, which in turn may be more prone to damage

Advantages of Telemetry system

Disadvantages of Telemetry system

  • Continious reading

  • can have gas and air velocity set up from the same sensor point with one system

  • Limited gas can be monitored

  • If mine power goes down, then system is on battery backup, which has limited life
