掘巷充填采煤围岩结构稳定性及移动规律

Structural Stability and Movement Law of Surrounding Rock for the Filling Coal Mining in Roadway

以燕家河矿为案例,分析了长壁机械化掘巷充填采煤技术的采煤具体方法及技术难点,并提出建立模型推导计算稳定性、移动规律的技术,目的是在开采作业中对围岩结构稳定性及上覆隔离水岩层的移动规律进行有效掌握。

Taking the Yanjiahe Coal Mine as a case, this paper analyzed the concrete methods and technical difficulties of the filling coal mining technology in the long wall mechanized roadway and put forward the model establishing technology to deduce the stability and movement law, aiming to effective control the structure stability of the surrounding rock and the movement law of the overlying aquiclude in the mining operation.
