摘要
为了分析研究井田构造区地应力对煤与瓦斯突出的影响,采用理论分析、现场实测和实验室试验并结合数值模拟结等方法,对九里山矿井地应力状态进行了划分,得出了九里山矿井田地应力分布规律,绘制井田构造区应力状态分区图。
In order to analyze the influence of ground stress in tectonic area on coal and gas outburst,by theoretical analysis,field measurement and laboratory experiment and combined with method of numerical simulation,the in- situ stress state in Jiulishan Mine was divided; the distribution laws of Jiulishan Mine ground stress is obtained; partition map of stress state in tectonic region of mining area is drawn.
