文家坡煤矿4号煤层瓦斯赋存规律探究

Research on Gas Occurrence Law of No. 4 Coal Seam in Wenjiapo Coal Mine

为了探究文家坡煤矿4号煤层瓦斯赋存规律,为矿井的安全生产提供必要的治理依据。依据矿井基础资料,从构造、煤层埋深、顶板岩性、煤层厚度和冲刷带影响等五个方面,探究了瓦斯的赋存规律。结果表明,矿井的瓦斯赋存受构造控制,瓦斯的含量与煤层埋深、煤层厚度正相关,与煤层顶板岩性具有弱相关性,冲刷带对煤层瓦斯含量的影响有限。研究成果可对今后文家坡煤矿安全生产措施的制定提供一定的科学依据。

In In order to explore the gas occurrence law of No.4 coal seam in Wenjiapo coal mine,and provide necessary governance basis for mine safety production.According to the basic data of the mine,the gas occurrence law is explored from the aspects of structure,coal seam burial depth,roof lithology,coal seam thickness,and the influence of the scour zone.The results show that the gas occurrence in the mine is controlled by the structure,and the gas content It has a positive correlation with the burial depth and thickness of the coal seam,and has a weak correlation with the lithology of the coal seam roof.The impact of the scour zone on the coal seam gas content is limited.The research results can provide a certain scientific basis for the formulation of safety production measures in Wenjiapo coal mine in the future.
