noise reduction in mining

Practical Guide for Mining Noise Control EastShore

During the normal operation, the fan speed on the mining status page is about 4320-4560 rpm and the tested noise about 1m away is about 76dB (A), which is almost equivalent to the noise at a busy transportation hub. Cooling Methods Prohibited by Engineers In terms of decibels, the noise generated by a single miner seems to be acceptable.Noise reduction during mining excavations for potash,The problem of noise generated during mining works consists of noise emitted from inside the canal and outside the canal. Interior noise is generated by mining machinery and equipment for coal mining and transportation. Outside noise is generated by the main fans, which must assure a constant, high dedusting efficiency.Noise Pollution and Its Control in Mining,The ambient noise level of the underground mining area is affected by the operation of the cutting machines, tub/conveyor movement and blasting of the coal. The movement of coaling machines and transport units-conveyor, tubs and transfer points caused audible noise which becomes disturbing underground because of the poor absorption by the walls.
