Noise affects the workers’ vascular system, the nervous system, and the digestive system and can cause irreversible damage to the hearing, even affecting the safety of production and operation efficiency.
Coal mining, extraction of coal deposits from the surface of Earth and from underground.. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of coal ...

1950’s. This technique was initially developed to degasify the coal seam ahead of mining operations. Similar trials were conducted in Australia during 1980 and by mid-1981 the Australlian Coal Industries Research Laboratories Limited (ACIRL) reported that “600 m longholes can be achieved on a regular basis”.
