NOISE CONTROLS FOR UNDERGROUND MINING

Learn how to reduce noise exposure in underground mining by implementing controls for the noise source, blocking the noise path, and enclosing noise receivers. This includes isolating flights from the pan/conveyor, using vibration damping materials, maintaining ventilation fans, installing sound absorptive materials, treating doors, and maintaining exhaust systems. OEM cabs and barriers can also be used to reduce sound levels emitted by underground mining equipment.

  3. APPLYING CONTROLS TO THE SOURCE (S) BLOCKING THE PATH (S) ENCLOSING THE RECEIVER NOISE EXPOSURE CAN BE REDUCED BY:

  4. FLIGHTS CAN BE ISOLATED FROM PAN / CONVEYOR WEAR STEEL VIBRATION DAMPING MATERIAL

  5. FLIGHTS ARE HELD IN PLACEON THE BOTTOM OF THE PAN WEAR STEEL VIBRATION DAMPING

  6. THE MINED MATERIAL LAYS BETWEEN THE WEAR STRIPS AND FURTHER HELPS TO REDUCE THE SOUND

  7. VENTILATION FANSSHOULD BE KEPT ISOLATED FROM FACE AREA

  8. Fan Silencers Should be Inspected and Cleaned as Necessary

  9. SOUND ABSORPTIVE MATERIALS CAN BE INSTALLED

  10. MUFFLERS CAN BE COVEREDDOORS CAN BE TREATED

  11. EXHAUST SYSTEMS SHOULD BE MAINTAINED

  12. Original Equipment Manufacturers Cabs Jumbo Drill L H D

  13. OEM CABS ARE BECOMING MORE COMMONIN UNDERGROUND MINING LHD SCALER

  14. CABS CAN ALSO BE FABRICATEDAND ACOUSTICALLY TREATED

  15. BARRIERS CAN BE USED TO BLOCK SOUND LEVELS EMITTED BY UNDERGROUND MINING EQUIPMENT

  16. HERE ARE TWO EXAMPLES OF THE USE OF BARRIERS JUMBO DRILL SCALER
