鲁班山矿是我国西南地区重要的大型矿山,属于高瓦斯矿。应用瓦斯地质系统理论,对鲁班山矿煤层瓦斯的生成、储集和保存地质条件和作用进行了研究。研究表明,地质构造、煤层厚度、煤层埋藏深度、煤层顶底板岩性、煤变质程度和煤中水份等是影响鲁班山矿瓦斯赋存的主要地质因素。瓦斯灾害预测应注意这些地质因素,尤其要重视各项地质因素的组合效应。
Luban Mine is an important large-scale mine in southwest China, belonging to high-gas mine. Applying the theory of gas geological system, the geological conditions and functions of gas production, storage and preservation in the coal seam of Luban Mountain Mine are studied. The results show that geological structure, thickness of coal seam, depth of coal seam burial, roof and floor rock of coal seam, degree of coal metamorphism and water content in coal are the main geological factors that affect the gas occurrence in Luban mine. Gas disaster prediction should pay attention to these geological factors, with particular attention to the combined effect of various geological factors.
