摘　　要：针对金鑫矿二1煤层瓦斯分布存在的不均衡特性,研究其瓦斯赋存规律。在大量瓦斯基础数据测试的基础上,结合矿井的地质构造和煤层情况,找出影响其瓦斯赋存的控制因素,即埋藏深度、地质构造、顶底板岩性和煤层露头等。结果表明:金鑫矿二1煤层瓦斯含量在倾向上随埋深增加而增大,瓦斯赋存总体呈"东南低,西北高"的规律。此结果对于金鑫矿制定合理有效的瓦斯防治措施具有指导作用。Aiming at malconformation of gas distribution in Jinxin coal mine Ⅱ1 coal seam, its gas occurrence law is investigated. Based on a lot of fundamental gas data, geological structure, and coal seam condition, it is found that the controlling factors affecting gas occurrence are coal seam depth, geological structure, roof and floor lithology, and coal seam outcrop, etc. The results show that： gas content of Ⅱ 1 coal seam in Jinxin coal mine increases with the depth augment along the dip. Gas occurrence presents the law of ＂southeast lower, northwest higher＂ from the global aspect. The research results contribute to making reasonable and effective gas prevention, and treatment measures avoid gas accidents for Jinxin coal mine.
