沿空掘巷窄煤柱稳定性控制技术

Stability Control Technology of Narrow Coal Pillars in a Mine Roadway

本文以某矿6302工作面轨道顺槽在不稳定覆岩下沿空掘巷为工程背景,对维护其窄煤柱侧的稳定性进行了研究,并且提出了对应的支护技术方案,在现场实际应用中也取得了良好的效果。可以为其他相似条件的矿井沿空掘巷提供参考借鉴。

In this paper, the ore track of the 6302 working face of a mine is used as the engineering background under the unstable overburden. The stability of the narrow coal pillar side is studied, and the corresponding supporting technical scheme is put forward. The application has also achieved good results. It can provide reference for other mines with similar conditions along the empty roadway.
