淮南煤田新集二矿煤系构造埋藏史及对瓦斯赋存的影响
Coal measure structure-burial history and its influence on gas occurrence in Xinji No.2 Mine of Huainan Coalfield
摘要
Abstract
This paper aims to investigate a deeper understanding about the hydrocarbon generation e-volution process and the gas geological distribution law behind deep coal-bearing stratum in Xinji No.2 Mine in Huainan Coalfield.The study involves reconstructing and analyzing the structural-burial,thermal evolution and hydrocarbon generation evolution processes of the lower permian in Shanxi formation based on the measured geological data of mine gas,and conducting a systematic study on the gas generation and escaping process,gas distribution characteristics and main controlling factors of No.1 coal seam.The re-sults show that the burial process of 1 coal seam shows a"V"type,and reaches the maximum burial depth about 3 740 m at the end of Indo-Chinese epoch,forming a large amount of gas,and following a process of continuous uplift and erosion,and slow escape of the gas.The gas content and pressure in 1 coal seam generally increase with depth.When the coal seam depth reaches 600 m,the gas content ex-ceeds 5.0 m3/t and the gas pressure reaches 0.74 MPa.The study points out that there is a risk of coal and gas outburst in No.1 coal seam at a depth of-600 m.关键词
