重庆市盐井二矿瓦斯赋存规律的构造控制分析

Tectonic Control Analysis of Gas Occurrence Laws in Chongqing Yanjing No.2 Mine

摘要: 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。

Abstract: In order to reveal gas occurrence laws and tectonic in Yanjing No.2 mine on control action of gas occurrence, based on the regional tectonic characteristic and its evolution, the paper analyzes the control action of geological structure factors such as tectonic evolution, structural types, roof and floor lithologic and hydrogeology on coalfield gas occurrence. The results show that twice gas generation process is the basis of current gas occurrence during the coalfield tectonic evolution.the control of later tectonic stress field evolution on coalfield tectonics development laws, sedimentary characteristics and groundwater, Changes the gas preservation conditions,which leads to the gas distribution differences.
