煤层注水可有效降低采掘工作面煤尘。主要介绍了煤层注水降尘机理、现场试验煤层注水情况并总结分析了煤层注水压力、注水时间对注水效果的影响。根据得出的合理注水压力及注水时间,对辛置煤矿613工作面进行了煤层注水设计并考察了注水降尘效果。
Coal seam water injection can effectively reduce the coal mining face dust. Mainly introduced the dust injection mechanism of coal seam, field test of water injection and the analysis of the coal injection pressure, water injection time on water injection effect. According to the reasonable water injection pressure and water injection time, coal seam water injection design was carried out on 613 working face of Xinzhi Coal Mine and the effect of dust injection by water injection was investigated.
