摘要
为了降低工作面粉尘,3302软煤层工作面实施了煤尘注水试验,通过注水方案的设计,直接采用静压水进行钻孔注水。实践结果表明,3302工作面全尘和呼吸性粉尘分别降低了81.4%和79.4%,降尘效果明显。
To reduce dust, the water inject experiment is implemented at 3302 working face with soft seam. The paper poresents the water injection scheme of borehole injection with static water pressure, which has respectively reduce the TSP and respirable dust by 81.4% and 79.4% at 3302 working face.
