摘要:
瓦斯压力是煤层瓦斯的重要基础参数,为了掌握煤层瓦斯压力,基于煤层瓦斯连续方程进行了瓦斯压力与煤层倾斜长度解析模型的推演,针对推演出的模型结合数值拟合方法建立了一种解析-数值耦合的瓦斯压力预判方法。为便于比较该方法与一般数值拟合的差异,选择了浅埋煤层及深部煤层两个差异化样本。不同样本下,一般数值拟合方法与耦合方法预判结果显示:样本Ⅰ中不同预判方法的相关性系数均在0.9874之上,样本Ⅱ中不同的预判模型相关性系数差异较大,耦合模型相关性系数最大为0.7786;样本Ⅰ中标准差数值及不同方法间差异均较小,样本Ⅱ中标差差异较明显;一般预判方法瓦斯压力增长梯度随倾斜长度的增加逐渐变大与实际不符,耦合方法瓦斯压力随倾斜长度增长趋于稳定与实际情况一致;不同预判模型下瓦斯压力生长曲线不因样本差异而有较大的波动。综合不同样本瓦斯压力预判结果可知,浅埋煤层瓦斯压力预判可应用线性回归方法,深部煤层瓦斯压力预判应用耦合方法与实际更相符。
Abstract:
Based on coal gas continuity equation, the analytical formulas about gas pressure and coal seam incline length were deduced, and a new pre-judge method of gas pressure was set up with numerical fitting. The general linear fitting and the coupling anticipation were compared with two differentiation samples including shallow coal seam and deep coal seam. The results showed that: the relative coefficients are all above 0.9874 in sample Ⅰ, and the maximum is 0.7786 in sample Ⅱ; the standard deviation has small difference in sample Ⅰ, and it has obvious difference in sample Ⅱ. The phenomenon that growth gradient of gas pressure under general models are all increasing with the incline length is inconsistent with the actual, but the fact that it tends to be stable under coupled linear model is consistent with the actual. The general change of growth curve is closely related to model selection, and it has no bigger different because of the sample difference. In comprehensive, the linear regression model of gas pressure anticipation can be used in shallow coal seam, while in deep coal seam, it will be more consistent with the actual if the coupled nonlinear model can be used.
