摘要
论述了河东矿1106回采工作面煤层注水工艺,选取进回风巷及回采工作面上多个测点进行了测定,从煤层水分增量和降尘率两个方面进行了粉尘的测定数据分析。分析结果为进回风巷各测点煤层水分增量大于1%,工作面4个测尘点的降尘率均在80%以上。
The water injecting process at No. 1106 mining face in Hedong Mine was described. The moisture increment and the dust removal rate of many sites in intake and return airways were measured. The measured data showed that the moisture increment was greater than 1 %, and the dust removal rate on four sites at the mining face were greater than 80 %.
