影响屯兰矿2^#、8^#煤层瓦斯赋存的地质因素分析

Effects of geological factors on gas storage in No.2 and 8 coal seams in Tunlan coal mine

通过对各煤层瓦斯赋存受地质构造、沉积、煤体赋存状态及煤质等影响因素进行单独分析,综合得出控制瓦斯赋存的主控因素,即关键地质体,以划分完成的地质单元为研究单位,具体探索屯兰矿2#、8#煤层瓦斯地质情况,为矿井瓦斯治理提供依据,确保矿井安全生产。

Based on the analysis of such geological factors as geological structure,sedimentation,occurrence state of coal mass and coal nature influencing the gas storage in different coal seams,it was concluded that the most important factor is the critical geological body.Through the research on the divided geological units,the gas storages in No.2 and 8 coal seams in Tunlan coal mine were discussed in detail,providing a scientific basis for the gas control and ensuring the safe production of coal mine.
