The harm of coal mine dust
The coal mine dust influence the safety of mine production, threatening the health of workers, it is one of the five major coal mind disasters.
Effective control of dust, dust concentration, improve the working environment, prevent dust accident, is an important link in coal mine production safety.
Coal production has developed rapidly in recent years, the level of mechanization has greatly improved, coal mine will produce large amounts of dust in tunneling, mining, transportation, safety production and the staff seriously threatens the mine health. Effective control of dust, dust concentration, improve the working environment, prevent dust accident, is an important link in coal mine production safety, grasp the Comprehensive Dustproof mine work, to promote mine safety production, is of great significance to protect the health of workers.
Coal mine dust is produced in the exploitation of coal mine, digging, mining and hoisting process, and long time suspended in the air in the rock and coal fine particles of dust, also referred to as.
Hazard of coal dust is mainly manifested in four aspects:
Coal spontaneous combustion and explosion, coal dust explosion risk exists generally, serious harm. Widespread China coal mine explosion in 2007, state-owned key coal mine 548 mine coal dust explosion hazard, accounted for 87.4%.
Serious occupational hazards. According to statistics, at present only the coal industry of pneumoconiosis patients have more than 200000, close to half of all industries in China Lung number, and each year is still growing, every year because of pneumoconiosis death in 2500 to 3000.
Reduce the visibility in the workplace. Under certain working face coal dust concentration is high, the visibility is very low, often lead to misoperation, increased incidence of industrial accidents.
Accelerating mechanical wear mine dust effects on mechanical equipment. In the accelerated wear machinery, precision instruments, life can. Control coal dust hazard has become the coal industry the most important things, and to control dust hazard, the most effective measure is to greatly reduce the dust concentration in the air of workplace.
