【摘要】：瓦斯是地质作用的产物，，地质演化控制瓦斯的生成、保存、赋存规律，实践证明瓦斯地质研究是治理瓦斯和防治瓦斯灾害的基础。 本论文运用板块构造理论、区域地质演化及瓦斯赋存构造逐级控制理论，研究了乌兰矿区地质构造对瓦斯赋存的影响；结合乌兰煤矿大量瓦斯地质资料和实测数据，编制矿井瓦斯地质图，研究矿井瓦斯赋存规律。 在编制乌兰煤矿瓦斯地质图的过程中，研究了断层、褶皱、煤层埋藏深度、顶底板岩性、煤层倾角等因素对瓦斯赋存的影响。通过综合分析得出了影响瓦斯含量的主控因素是埋藏深度，并采用多元线性回归分析方法，建立数学模型，通过逐步回归的方法得出了瓦斯含量于埋深的线性关系；在上述的基础上对乌兰煤矿相对瓦斯涌出量进行了预测；并对其煤层气资源量进行了预计，结果与事实情况吻合。本文的研究结论对乌兰矿及临近矿井的瓦斯治理工作具有指导性意义。
[Abstract]:Gas is the product of geological action. Geological evolution controls the generation, preservation and occurrence of gas. The practice proves that gas geology research is the basis of gas control and gas disaster prevention. In this paper, the influence of geological structure on gas occurrence in Wu Lan mining area is studied by using plate tectonics theory, regional geological evolution and gas occurrence structure control theory. Combined with a large amount of gas geological data and measured data in Wu Lan coal mine, the gas geological map of mine is worked out and the law of gas occurrence in mine is studied. In the course of compiling gas geological map of Wu Lan coal mine, the influence of fault, fold, buried depth of coal seam, roof and floor rock property, coal seam dip angle on gas occurrence is studied. Through comprehensive analysis, it is concluded that the main controlling factor of gas content is buried depth, and the mathematical model is established by multivariate linear regression analysis, and the linear relationship between gas content and buried depth is obtained by stepwise regression method. On the basis of the above, the relative gas emission of Wu Lan coal mine is forecasted, and the CBM resource quantity is predicted. The results are in agreement with the facts. The conclusion of this paper is of guiding significance to the gas control work of Wu Lan mine and adjacent mine.
