Feb 03, 2021 In most cases, noise pollution is manmade. The causes include: Mining operations: Noise of higher intensity is formed from mining operations, such as blasting, drilling, crushing, and excavation. Industrialization: Most industries use big machines, generators, compressors, exhaust fans, and grinding mills that produce loud noises. Poor urban planning: Proximity to industrial areas, …Objective: To develop effective noise controls for continuous mining machines (CMMs) to reduce worker noise exposure. Background: Noise-induced hearing loss (NIHL) is an occupational illness caused by chronic exposure to excessive sound levels. For underground coal mine workers, NIHL continues to be a serious health issue.

Noise generated by continuous mining machines in underground coal production is an important health hazard. Bureau of Mines Contract J0387229 covers investigation of this noise through laboratory tests of simulated cutting operations and through in-mine noise measurements.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.
