摘要
水力挤出的封孔深度是影响消突效果的重要因素之一,以理论分析为基础,结合韩城桑树坪煤矿的实际情况,经过实践考察分析,确定了桑树坪煤矿水力挤出的合理封孔深度,取得了明显的效果,实现了安全快速掘进。
The depth of sealing hole is a very important factor in hydraulic screen; according to the condition of Sang Shu - ping coal mine, base the theoretically analyse and though the checkout, make sure the logical depth of sealing hole of hydraulic screen in Sang shu-ping coal mine, good effect was obtained, and carrying out rapid excavation.
