摘要
平舒煤矿主采煤层7号煤瓦斯、地质情况较复杂,底板突水现象严重,该矿试验无煤柱开采技术。本文根据该矿瓦斯治理经验,结合无煤柱开采漏风情况,制定合理的瓦斯抽放方法,并结合瓦斯监测预警技术,保证了矿井瓦斯安全。
The gas and geological conditions of No. 7 coal seam in Pingshu Coal Mine are complex, and the floor water inrush from floor is serious. The coal pillar-free mining technology is tested in Pingshu Coal Mine. Based on the experience of gas control in this mine and the situation of air leakage in coal pillar-free mining, this paper formulates a reasonable gas drainage method, and combines with gas monitoring and early warning technology to ensure mine gas safety.
