摘　　要：根据煤矿实际开采过程中遇到的坚硬顶板问题,详细地分析了坚硬顶板综合机械化采煤工作面的矿压现状,同时利用FLAC3D数值模拟软件对坚硬顶板和爆破处理后顶板的应力进行了数值模拟分析,并判断了不同推进距离顶板的破坏方式,在理论的支持上,将超前预爆破处理坚硬顶板技术运用到实际的坚硬顶板处理问题上,取得了良好的效果,为实际工程提供了重要的理论和参数。According to the problem of hard roof encountered in the actual mining process of coal mine, this paper analyzes in detail the mine pressure status of the hard roof comprehensive mechanized coal mining face, and uses FLAC3 D numerical simulation software to carry out numerical simulation analysis on the stress of the hard roof and the roof after blasting treatment, and judges the failure mode of the roof with different advancing distance. In the theoretical support, the advanced pre-blasting technology is applied to the actual treatment of hard roof, which has achieved good results and provides important theoretical and parameter reference for practical engineering.
