摘要
针对演马庄矿石门揭煤存在突出危险性大、技术工艺复杂的问题,采用抽采钻孔修复增透技术,对石门揭煤区域设计的抽采钻孔进行水力冲孔修复,提高了钻孔的抽采效果,实现了石门揭煤区域储层的快速消突,大大提高了高突煤层石门揭煤的速度,较好地解决了煤矿井下采掘作业接替紧张的现状。
Aiming at the high outburst risk and complex technical procedure of cross-hole coal mining at Yanmazhuang Mine, through the use of drainage drilling technology to increase permeability, hydraulic flushing borehole repairing was used for de- signed water pumping coal area of cross-hole, the drilling pumping effect was enhanced, rapid outburst removing of cross-hole was achieving, which greatly improved the uncovering speed of cross-hole of high outburst coal seams, the present situation of mining operation replacing tension in coal mines could also be solved better.
