摘要
在分析淮北矿区瓦斯与地质资料的基础上,运用瓦斯赋存构造控制理论,研究了淮北矿区构造及其演化对瓦斯赋存的影响。研究表明:淮北矿区瓦斯赋存严格受构造控制,主要受EW向、NE-NNE向和徐宿弧形构造控制。EW向构造对瓦斯赋存的影响较小;NE-NNE向构造是影响淮北矿区瓦斯赋存的主控构造;徐宿弧形构造(安徽段)对瓦斯赋存的影响呈现出两翼煤与瓦斯突出严重,中部煤层严重风化的特征。
Based on the ana]ysis of gas and geological data in Hoaibei Mining Area, the influence of structure and evoh, tion on gas oc- currence in Huaibei Mining Area was studied with the theory of the teclonic control on gas oeeurrence. The results showed that the gas oceurrence was strictly eontrolled by the structure in Huaibei Mining Area, which was mainly controlled by the EW direction, NE - NNE direc.tion and Xusu arc structure. The EW direction struceture had little influence on the gas occurrence： The NE - NNE direction structure was the main controlling structure which affected the gas occurrence in Huaibei Mining Area. The characteristics of lhe influ- ence of the Xusu arc structure on the gas occurrence （ Anhui segment） showed that serious coal and gas outburst appeared in the two wings and severe weathering of the coal seam appeared in central.
