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 analysis of the gas and geological data in Huaibei mining area, the paper uses the tectonic control theory of gas occurrence to study the influence of the structure and evolution of Huaibei mining area on gas occurrence. The results show that the gas occurrence in Huaibei Mining Area is strictly controlled by tectonics and controlled mainly by EW direction, NE-NNE direction and Xucun arc structure. EW structure has little influence on gas occurrence; NE-NNE structure is the dominant structure that affects gas occurrence in Huaibei mining area; influence of XuCu arc structure (Anhui section) on gas occurrence shows coal and gas Seriously prominent, the central coal serious weathering characteristics.
