综采工作面过大断层仰采技术研究

Study on the Technology of Up-dip Minging of Oversize Fault in Fully-Mechanized Mining Face

综采工作面在回采过程中经常遇断层破碎带,在过断层破碎带期间若不采取合理有效的回采技术,不仅降低工作面回采效率,加大设备损坏程度,而且很容易发生安全事故。针对这一施工难题,店坪煤矿在5-302工作面回采期间过断层破碎带时,研究决定采用仰采工艺及合理支护措施过断层破碎带,取得了显著成效。

Big fault fracture zone is often encountered in the process of extraction of fully mechanized working face,during the period of passing through large fault fracture zone,if reasonable effective stoping technology is not taken,not only the efficiency of mining face will be reduced,but equipment damage degree can also be increased,and it's easy to bring about major coal mine safety accidents.To solve the construction problems,Dianping Coal Mine,during 5-302 mining face passing through the fault fracture zone,after the analysis and research,decides to use up-dip mining technology and the reasonable supporting measures when the face passes through fault fracture zone.It has achieved a remarkable success by practice.
