| 摘 要： | 通过煤体注水数值模拟表明,当在一定压力作用下钻孔注水时,其渗透范围随着孔径、注水时间的增大而增大,埋深对其影响不大；但对水流渗透影响最大的为岩层中节理、裂隙的发育程度,当节理裂隙较为发育时,水流可渗透到整个煤层.通过现场注水试验,三交河煤矿504工作面进行煤体注水完全达到了煤层内含水率增加1％的要求,总尘浓度降低了65...

| Abstract: | Numerical simulation of water flooding in coal seam shows that osmotic range got bigger with pore diameter and injection time under certain pressure of water flooding, and embedded depth showed little effect on it. but, the most factors with the inflence of osmosis were joint fssure development of rocks. Currents could penetrat into the whole seam as the joint fssure development is fine. After water fooding tests were carrying out on the spot in the Face 504, the increase of seam water content reached to 1% and the total dust concentration was reduced by 65.6 percent when using coal-dust suppressants. |
