顺通煤矿W1151综采工作面开采的是A_5煤层,在生产过程中产生的大量的粉尘具有爆炸性,对该煤层进行静压注水降尘技术试验研究,试验取得了良好的效果:煤体平均含水率增加2.84%,降尘率达到60%~90%。大大降低了工作面回采时的粉尘浓度,对于防治粉尘爆炸事故具有重要的意义。
The W1151 fully mechanized coal mining face of the coal mine is A_5 coal seam, a large amount of dust generated in the production process is explosive, the experimental study on the dust suppression technology of hydrostatic water injection of the coal seam, the test has achieved good results: the average water content of coal Increase 2.84%, dust reduction rate of 60% to 90%. Greatly reducing the concentration of dust when mining face, for the prevention and control of dust explosion accident is of great significance.
