摘 要:阳泉矿区为高瓦斯矿区,瓦斯地质灾害成为威胁矿区当前安全高效生产的主要因素。采区主要表现为较高的瓦斯含量和瓦斯压力,瓦斯喷出和瓦斯突出等现象较为严重。文章在前期矿区地应力测量的基础上,通过地应力的分析、计算和数值模拟,揭示研究区主采煤层的地应力场空间分布状况,并结合研究区构造条件、煤层埋深、围岩封闭性和构造煤发育情况,最终对矿井煤与瓦斯突出危险性进行了预测预报,对指导矿井安全生产具有重要意义。As a high gas area,gas geological disasters have become the main factor threatening the safe and efficient production in Yangquan mining area.The area is mainly characteristic of high gas content,high pressure,and severe gas emission and outburst.This study is based on the previous ground stress measurement of the area.The analysis,calculation,and numerical simulation of the ground stress revealed the spatial distribution of the ground stress field of the main coal seam.Combined with the tectonic condition,the paper predicts the buried depth of the coal seam,the confinement of surrounding rock,and the development of tectonic coal,and the coal and gas outburst risks,which is of great significance for guiding the safe production in the mines.
