摘要
在地下煤炭资源开采过程中,采场和围岩压力显现规律及控制是采矿领域最重要的课题之一。结合华胜煤业实际地质条件对工作面回采围岩稳定性进行理论分析,研究巷道和煤柱受力位移变形机理,并应用FLAC3D数值模拟软件分析煤柱在开采过程中应力分布及水平位移情况,以期为同类型围岩煤矿研究提供一定的参考。
In the process of mining underground coal resources,the law and control of pressure appearance of stope and surround-ing rock is one of the most important topics in the mining field.Combined with the actual geological conditions of Huasheng Coal Industry Co.,Ltd.,this paper made a theoretical analysis of the surrounding rock stability of the working face,studied the deformation mechanism of the stress displacement of the roadway and coal pillar,and applied FLAC3D numerical simulation software to analyze the stress distribution and horizontal displacement of the coal pillar in the mining process,in order to provide some reference for the study of the same type of surrounding rock coal mine.
