古书院煤矿综采工作面顶板控制技术分析

Analysis and Application of Roof Control Technology in Complex Fully Mechanized Coal Face

结合古书院煤矿综采工作面实际情况,介绍了综采工作面初采阶段超深孔爆破强制放顶方法,探讨了综采工作面过空巷、过薄基岩顶板处理手段以及末采阶段顶板管理方法。

In order to prevent the large-scale collapse of the roof in the fully mechanized mining face in complicated geological conditions, the complex reinforcement of the overpass and thin bedrock roadway, the frequent collapse failure in the end mining stage, and the distant empty roof interval in the recovery stage, etc., the paper introduces some technical methods such as ultra-deep hole blasting forced topping in the initial mining stage, accurate evaluation of the first pressure of the roof, the treatment of the roof of the overpass, the treatment of the thin bedrock roof, and the treatment of the final roof, etc., which effectively curbed the emergence of roof disasters.
