超前抽巷法在综采工作面过断层中应用

The Application of Advance Extraction Method in Fully Mechanized Face Passing Through Fault

针对9102工作面传统方法过F2断层时回采效率低、机械破岩量大、过断层周期长等技术难题,提出了采用超前抽巷法,提前将断层带的岩石去除掉,将过断层施工转化为过空巷施工,保证了过断层施工安全,提高了回采效率,取得了显著应用成效。

In view of the technical problems such as low mining efficiency,large amount of mechanical rock breaking and long period of passing through fault when the traditional method of 9102 working face passes through F2 fault,this paper puts forward the method of advance extraction,which can remove the rock in the fault zone in advance,transform the construction of passing through fault into the construction of passing through empty lane,ensure the safety of the construction of passing through fault,improve the mining efficiency and achieve remarkable application results.
