摘要
为了查明煤矿瓦斯地质规律,以更好地指导煤矿瓦斯灾害,以淮南煤田潘一矿为研究对象,划分了瓦斯地质单元,研究结果表明:淮南煤田潘一矿煤系地层主要受晚三叠世和晚侏罗-早白垩世时期构造运动的改造,其内部产生了不同时期的构造形迹,以矿井内主要断层F4、F5为界,将其划分为3个瓦斯地质单元,对划分出的3个瓦斯地质单元的瓦斯地质规律进行了研究,揭示了各瓦斯地质单元内构造煤分布特征、瓦斯含量与瓦斯压力、瓦斯风化带深度及瓦斯动力学现象,对该矿瓦斯灾害防治提供了指导。
In order to prove the mine gas geological law to well guide prevention and control of mine gas disaster,taking Panyi Mine of Huainan Coalfield as a study object,the mine gas geological unit of Panyi Mine was divided.The study results showed that the coal measure strata of Panyi Mine in Huainan Coalfield were reconstructed mainly by the tectonic movements during the Late Triassic and Late Jurassic-Early Cretaceous and tectonic features of different period occurred in the internal of the strata.Based on major fault F4 and fault F5 in the mine as a boundary,three gas geological units were divided.A study was conducted on the gas geological law of the three gas geological u-nits.The structure coal distribution law,gas content and gas pressure,gas weathering zone depth and gas dynamics phenomenon in each gas geological unit were revealed and could provide guidance to the prevention and control of the mine gas disaster.
