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。

The gas is a product of geological processes, gas generation, preservation and occurrence are controlled by geological evolution. It has been proved that gas-geology research is the basis of how to solve the gas disaster. This paper using plate tectonic theory, regional geological evolution and gas occurrence tectonic cascade control theory, studies the mining area, WuLan mine geological structures of gas occurrence of control; Combined with a geological data and coal gas, preparation of measured data of mine gas geology map, Research mine gas mineralizing rules. Through compileding mine gas geology map of, studies the fault, drape, coal buried depth, roof and floor lithology and the tilt Angle of coal,to gas occurrence the influence of multiple linear regression analysis, using the multiple linear regression analysis method，Established the mathematical model，using stepwise regression method have the influence of the main controlling factors of the gas content is buried depth; Respectively with gas geology statistics to predict the absolute gas emission in WuLan coal；It calculating the methane resource in coal-bed .Preliminary forecast for coal. The results accord with the truth.This article research conclusion to ulam ore and is near mine gas control work has guiding significance.
