王庄煤业综采工作面过向斜构造技术应用

Application of Syncline Crossing Technology in Fully Mechanized Mining Face of Wangzhuang Coal Industry Co.,Ltd.

为保障3505综采工作面安全通过向斜构造,减少煤炭资源浪费,分析了回采过向斜构造的技术难题,实施了对构造影响区域煤壁进行预注浆加固,充填工作面旧巷和工作面仰采注浆加固的方案,确保了回采过程中的作业安全,避免了因绕采而带来的回采效率低的问题。

In order to ensure the safety of 3505 fully mechanized mining face passing through syncline structure and reduce the waste of coal resources,this paper analyzed the technical problems of mining through syncline structure,and implemented the scheme of pre-grouting reinforcement of coal wall in the area affected by structure,filling the old roadway of working face and grouting reinforcement of upward mining of working face,so as to ensure the operation safety in the process of mining and avoid the problem of low mining efficiency caused by surrounding mining.
