综采顺拉工作面中间巷过断层方法

Method of Crossing Fault in Middle Lane of Fully Mechanized Working Face

针对中间巷道在顺拉工作面保持一定错距生产期间出现断层的情况,分析过断层的关键点,采取理论与实践相结合的方法,提出了综采顺拉工作面中间巷过断层区域提前在断层处进行顶板加固与超前外提前进行落底的方法相结合,并收集分析采取措施前后的矿压观测数据进行对比,得出21011工作面中间巷过断层时采用此种支护方式,能有效地支护中间巷顶、底板,使顶板下沉和聚帮鼓底的现象得到很大改观。

In the middle roadway in the face to maintain a certain situation from the wrong fault duringproduction, analyzed the key points of the fault, adopting the method of combining theory with practice,fully mechanized long wall face along the middle lane in advance and fault region advanced ahead atthe end of the combination method of roof reinforcement in faults. The collection and analysis, to takemeasures before and after the comparison of mine pressure observation data, the 21011 working face ofintermediate roadway through fault with the supporting way, can effectively support the middle ofroadway roof and floor, the roof subsidence and poly help the drum bottom phenomenon has beengreatly improved.
