Compared to the three mining machines used at the mine previously, using a surface miner significantly reduced noise emissions. Mining with the 4200 SM likewise has a positive impact on dust emissions. In contrast to the dozers and wheel loader all of which generate considerable quantities of dust that impact the work environment the dust ...
The continuous mining method, an innovation from the late 19th and 20th century, eliminates the drilling and blasting operations found in conventional mining. This method uses a machine called a continuous miner. It continually extracts the coal, while loading onto a conveyor system. Coal Production Regions.
hearing loss (NIHL), it is still a problem in the coal mining industry. The Mine Safety and Health Administration noise standard (30 CFR. 3. 3. Code of Federal Regulations. See CFR in references. 62), which was enacted in September 2000, is aimed at reducing NIHL in the mining industry. To address NIHL in various aspects of coal mining and ...
