通过分析矿区地质构造演化及构造控制,研究了山西某煤矿9+10号煤层的瓦斯地质规律,预测瓦斯含量分布,为防治瓦斯灾害提供科学依据.结果表明随着开采深度的增加、地质构造环境的变化以及采煤机械化程度的增加,瓦斯涌出量也会随之变化甚至增加,因此有必要在今后加强通风管理,防止局部瓦斯积聚,保证矿井安全生产.“,”In order to provide scientific basis for prevention and control of gas disasters, through analysis of geological tectonic evolution and tectonic control, a certain coal mine in Shanxi No. 9 + 10 coal seam gas geology rule was studied, the gas concentration distribution was forecasted, the results showed that with the increase of mining depth, the change of geological tectonic environment and the increase of coal mining mechanization degree, also increased along with the change and even the gas emission. So, it was necessary to strengthen the administration of the ventilation in the future to prevent the local gas accumulation and guarantee the mine safety production.
