摘要
基于瓦斯构造逐级控制理论,在研究峻德井田区域构造演化规律及瓦斯赋存规律的基础上,系统研究了矿井构造煤发育特征,并构建了以煤层埋深、构造煤厚度以及坚固性系数为自变量的瓦斯含量多元回归模型。研究结果表明:构造煤发育特征是影响煤层瓦斯变化的关键因素,瓦斯含量随构造煤厚度变化梯度为0.96m3/t/m。
Based on the gas tectonic gradual control theory, based on the study of Junde minefield regional structure evolution and gas occurrence regularity, systematically study the characteristics of mine tectonic coal, and construct the gas content of multivariate regression model that take the coal seam depth, the thickness of the structure coal and firmness coefficient as the independent variable. The results show that the development characteristics of tectonic coal are the key factors that affect the variation of coalbed methane, and the gradient of gas content varies with the thickness of tectonic coal is 0.96m^3/t/m.
