摘要
针对赵官煤矿瓦斯分布不均,局部瓦斯积聚的情况,从区域煤田到矿区地质再到矿井瓦斯地质,应用瓦斯地质逐级控制理论,较好的阐述了赵官煤矿的瓦斯富集区域及其井田瓦斯赋存特点。通过对影响赵官煤矿瓦斯赋存规律各主控因素的综合分析,得出煤层埋藏深度、岩浆岩侵入状况、断层基本形态、煤层顶底板岩性是影响瓦斯赋存规律的主要因素,并提出了针对性的区域瓦斯灾害防治技术措施。
In view of uneven gas distribution and local gas accumulation in Zhaoguan Coal Mine,from regional coal field to mine geology and then to mine gas geology,the gas accumulation area and gas occurrence characteristics in Zhaoguan Coal Mine are described by applying the gas geology control theory step by step.Through the comprehensive analysis of the main controlling factors affecting the gas occurrence rule of Zhaoguan Coal Mine,the buried depth of coal seam,the intruding condition of magmatic rock,the basic form of fault and the lithology of the roof and floor of coal seam are the main factors affecting the gas occurrence rule,and the corresponding technical measures for regional gas disaster prevention and control are proposed.
