采用板块构造理论和区域构造演化理论,研究了永夏矿区陈四楼煤矿矿井构造演化,分析了构造变形、构造发育及构造控制瓦斯特征,统计了该矿近年来瓦斯涌出量及瓦斯含量数据,分析了影响该矿井瓦斯含量变化的主要原因,确定了影响二2煤层瓦斯分布的主要因素,并对矿井瓦斯地质单元进行了划分,以该矿已发生的煤与瓦斯突出事故为例,从瓦斯地质方面进行了分析,从而做到有的放矢地防治瓦斯灾害。
Based on plate tectonics theory and regional tectonic evolution theory, the mine tectonic evolution of coal seam in Chensilou of Yongxia mining area was studied. The characteristics of tectonic deformation, tectonic development and tectonic control were analyzed. The gas emission and gas content of the mine in recent years , Analyzed the main factors affecting the gas content in the mine, determined the main factors affecting the gas distribution in No.22 coal seam, and classified the gas geological units in the mine. Taking the coal and gas outburst accidents in the mine as an example, Gas geological aspects were analyzed, so as to achieve targeted control of gas disasters.
