综采工作面边扩帮边安装法在清水营煤矿的应用

The application study of the methods of broadening and installing of fully-mechanized mining face

针对"三软煤层"、煤层顶板含水层、顶板压力大、底板岩石遇水膨胀等复杂的地质条件,为实现综采工作面切眼施工及安装速度最大化及有效对顶板进行支护,提出了综采工作面采用"边扩帮边安装"的施工技术方案,并进行了应用研究,以提高在复杂地质条件下综采工作面的安装速度及有效对顶板进行支护。

Aiming at the complicated geographical condition such as Three Soft Rock Layers,coal seam roof water-bearing stratum,baseboard rock will expand when meeting water,in order to realize the cut construction of full-mechanized mining face ,the maximization of the installation speed and supporting on the roof effectively,this text puts forward the adoption of construction technical plan of broadening and installing for the full-mechanized mining face and studies the application to raise the installation speed of the full-mechanized mining face under the complicated geographical situation and supports the roof effectively.
