淮北宿县矿区朱仙庄矿瓦斯压力分布规律研究

Study of Gas Pressure Distribution Rule of Zhuxianzhuang Mine of Suxian Mining Area in Huaibei

根据淮北宿县矿区朱仙庄矿的地质背景、瓦斯压力测试数据等统计资料,分析了朱仙庄矿瓦斯压力与地质构造、顶底板岩性、煤层赋存的关系。结果表明,朱仙庄矿煤层瓦斯压力整体随深度增大而增大,瓦斯压力明显受构造控制,大褶曲、断层等控制矿井瓦斯压力,煤层岩浆岩侵入带,瓦斯压力低。

According to the geological background of Zhuxianzhuang Coal Mine of Huaibei Suxian Mining Area, gas pressure test data and statistical data, the relationship between Zhuxianzhuang Mine gas pressure and the geological structures, lithology of roof and floor, coal seam existence is analyzed. The results show that Zhuxianzbuang Mine coal seam gas pressure increases with depth, gas pressure was controlled by structure, large folds and faults control mine gas pressure, coal seam magmatic intrusion belt, the gas pressure is lower.
