为了揭示盐井二矿瓦斯赋存规律及构造对瓦斯赋存的控制作用,基于区域构造特征及其演化,分析了构造演化、构造类型、顶底板岩性及水文地质特征等地质构造因素对井田瓦斯赋存的控制作用。结果表明:井田的构造演化过程中的2次生气过程是现今瓦斯赋存的基础,后期的构造应力场演化对井田构造发育规律、沉积特征及地下水径流的控制,改变了瓦斯的保存条件,从而造成瓦斯分布的差异性。
In order to reveal the regularity of gas occurrence and the control effect of tectonics on the gas occurrence in the Second Mine of Salt Mine, based on the regional tectonic features and evolution, the influence of geological and tectonic factors such as tectonic evolution, tectonic type, roof and floor lithology and hydrogeological features, Presence of the control role. The results show that the secondary gas generation during the tectonic evolution of the minefield is the basis of current gas occurrence. The evolution of tectonic stress field in the later period controls the tectonic development law, sedimentary characteristics and groundwater runoff of the mine field, and changes the gas storage conditions. Resulting in the difference of gas distribution.
