回采工作面补切眼内掏槽过断层技术研究与实践

The research and practice of the crossing fault technology by opening off cut and slotting at mining face

介绍了枣矿集团高庄煤业有限公司3上1101工作面采用补切眼内掏槽过13.5m(走向346°、倾向76°、倾角55°)岩石大断层的技术,使顶板得到了有效控制,加快了工作面推进速度。

This paper introduces the technology of crossing large fault by opening off cut and slotting at Gaozhuang coal mine group Co.,Ltd.3 1101 face,successfully crossed the large rock fault of 13.5 meters（to 346 °,76 °,dip Angle to 55 °）.By using the crossing fault technology,the roof was effectively controlled;the speed of face advance was speeded up.
