Applying controls to the source, blocking the path, and enclosing the receiver can reduce noise exposure in underground mining. This includes isolating flights from the pan/conveyor, using steel vibration damping material, installing sound absorptive materials, maintaining exhaust systems, and using OEM cabs and barriers.

APPLYING CONTROLS TO THE SOURCE (S) BLOCKING THE PATH (S) ENCLOSING THE RECEIVER NOISE EXPOSURE CAN BE REDUCED BY:
FLIGHTS CAN BE ISOLATED FROM PAN / CONVEYOR WEAR STEEL VIBRATION DAMPING MATERIAL
FLIGHTS ARE HELD IN PLACEON THE BOTTOM OF THE PAN WEAR STEEL VIBRATION DAMPING
THE MINED MATERIAL LAYS BETWEEN THE WEAR STRIPS AND FURTHER HELPS TO REDUCE THE SOUND
Original Equipment Manufacturers Cabs Jumbo Drill L H D
OEM CABS ARE BECOMING MORE COMMONIN UNDERGROUND MINING LHD SCALER
BARRIERS CAN BE USED TO BLOCK SOUND LEVELS EMITTED BY UNDERGROUND MINING EQUIPMENT
HERE ARE TWO EXAMPLES OF THE USE OF BARRIERS JUMBO DRILL SCALER
