顶板控制和覆岩破裂规律研究是井下开采支护的理论基础。以张家口蔚州煤矿地下气化场煤层为研究对象,利用计算机仿真技术模拟了“三带”发育、覆岩结构规律、围岩剪应力分布、煤层支撑压力分布、燃空区厚岩层载荷分布以及覆岩垂直位移变化规律。该研究为煤矿井下气化场煤层覆岩支护措施的设计提供了参考。
Roof control and overburden rock rupture law is the theoretical basis of underground mining support. Taking the coal seam of the underground gasification field of Weizhou coal mine in Zhangjiakou as the research object, the computer simulation technique was used to simulate the development of the “three zones”, the law of the overburden rock, the stress distribution of the surrounding rock, the supporting pressure distribution of the coal seam, Distribution and overburden vertical displacement changes. This study provides a reference for the design of coal seam overburden support measures in coal mine gasification field.
