摘要
依据马兰矿8#煤层的瓦斯地质资料,在对瓦斯富集影响因素进行定性、半定量分析的基础上,采用层次分析方法,对煤层埋深、地质构造、顶底板岩性、水动力条件、煤岩变质程度等对瓦斯富集的影响权重进行了定量计算。研究结果表明:煤层埋深和水动力条件是控制该矿瓦斯赋存的主要因素。
Based on the gas geological data of Malan Mine,the influence factors of coal seam buried depth,fault,fold,roof and floor lithology,hydrodynamic conditions,metamorphic degree of coal and rock that impact the gas enrichment were analyzed,through the method of combining quantitative analysis and qualitative analysis. At the same time,the weight was counted quantificationally. The results show that the buried depth of coal seam and the hydrodynamic condition are the main factors controlling the mine gas occurrence.
