采用理论分析、现场实测及经验公式计算的方法对阿刀亥煤矿东部采区1193西翼工作面顺槽南、北巷掘进巷道的煤壁瓦斯涌出规律进行研究,通过南、北巷掘进面煤壁瓦斯涌出情况实测及对比分析,得出了沿煤层顶、底板掘进的不同巷道其煤壁瓦斯涌出规律及差异性,为急倾斜特厚煤层不同掘进巷道的瓦斯防治提供了一定的技术参考。
By using theoretical analysis, field measurement and empirical formula calculation, the gas emission law of coal wall in the south and north roadway along the working face of 1193 west wing of Adahai coal mining area is studied. Through the excavation face of south and north lane The gas emission from the coal seam was measured and compared, and the law of gas emission and its difference in different roadways along the top and bottom of the coal seam were obtained, which provided certain measures for gas prevention and control in different tunneling of steeply-inclined ultra-thick coal seam Technical reference.
