摘　　要：针对义煤集团义马矿区冲击地压矿井和新安矿区高瓦斯矿井安全高效开采解放层技术的需要,以新安矿区鑫山小型煤矿极薄煤层煤层开采为工程背景,对薄煤层开采后顶板岩层的移动和应力分布情况进行数值模拟分析,研究解放层开采后工作面顶板移动规律和围岩应力分布情况,为冲击地压矿井和高瓦斯矿井解放层开采设备选型、采面布置、围岩控制等提供理论指导和技术支撑。In view of the need of high gas mine safety and high efficiency mining and liberation layer technology in the Yima mining area of Yihua Coal Group and Xinan mining area,the mining of extremely thin coal seam in Xinshan small coal mine in Xinan mining area is the engineering background. The movement and stress distribution of the roof layer after mining of thin coal seam are simulated and analyzed,and the movement laws of the top plate and the stress distribution of surrounding rock on the working surface after mining of liberated layer are studied. It provides theoretical guidance and technical support for the selection,surface arrangement,and surrounding rock control of mine and high gas mine liberation.
