穿越小窑破坏区掘进技术研究

Research on Tunneling Technology for Passing through Destructive Area in Small Kiln

开采煤炭时,当经过小窑破坏区时,周围岩层的稳定性比较差,常常会发生采区顶板下落和离层的现象,这对后续的支护与掘进工作造成了一定的影响,加大了矿井的开采难度。下面将对A矿5号煤层穿越小窑破坏区掘进技术进行简要阐述,以期为日后相关工作顺利进行提供参考。

The stability of the surrounding rock formations is relatively poor when passing through the destructive area of small kiln during mining,and the roof falling and separation of the mining area often occur,which has a certain impact on the subsequent support and tunneling work,and increases the difficulty of mining in the mine.This paper made a brief description of the tunneling technology for passing through destructive area in small kiln of No.5 coal seam in A Mine,which provide a reference for the smooth progress of related work in the future.
