根据义马中部井田瓦斯地质规律,选取埋深、开采强度、开采顺序和煤层厚度作为自变量,瓦斯涌出量为目标量,构建自变量矩阵和参考序列,进行瓦斯涌出量影响因素灰色关联度分析;由于各瓦斯地质影响因素与瓦斯涌出量的高度非线性关系,将各影响因素进行归一化处理,建立优化神经网络预测瓦斯涌出量数值模型,样本训练收敛速度快,误差在0.12%以内,并用此模型对耿村井田深部煤层瓦斯涌出量进行了预测。
根據義馬中部井田瓦斯地質規律,選取埋深、開採彊度、開採順序和煤層厚度作為自變量,瓦斯湧齣量為目標量,構建自變量矩陣和參攷序列,進行瓦斯湧齣量影響因素灰色關聯度分析;由于各瓦斯地質影響因素與瓦斯湧齣量的高度非線性關繫,將各影響因素進行歸一化處理,建立優化神經網絡預測瓦斯湧齣量數值模型,樣本訓練收斂速度快,誤差在0.12%以內,併用此模型對耿村井田深部煤層瓦斯湧齣量進行瞭預測。

An independent matrix and reference sequence were constituted according to the regularity of coal-bed gas geology in the middle of Yima coal field and by selecting the buried depth of coal seams, the mining intensity, mining sequence and the thickness of coal seam as the independent valuables and the gas emission as the objective variable, the grey correlation analysis on the influence factors of the gas emission was made. Since each influence factor of the coal-bed gas geology has a high nonlinear relation with gas emission, normalized treatment for the influence of each factor was made, a mathematical model based on the optimized neural network was set up for gas emission prediction, the convergence speed of the sample training of the model is fast, with the error less than 0. 12%,and this model was used for the gas emission prediction in deep coal seams in Gengcun coal field.
