掘进工作面瓦斯流动场及涌出规律探讨

DISCUSSION OF THE FLOWING GAS DISTRIBUTION AND THE FLOWING RULE ON THE HEADING FACE

摘要: 建立了一般状态下瓦斯在实际煤层中的单向流动场模型,推出了瓦斯涌出量的方程式。然后根据工作面的实际情况,推出该工作面的瓦斯流动场模型。同时根据实测数据计算出的瓦斯涌出量,利用数理统计中的非线性回归理论建立了该工作面的瓦斯涌出量回归模型。

Abstract: The flowing gas model in the actual coal Seams in the normal situation is founded with single direction forms.he equation on the quantity of flowing gas is worked out.Then according to the actual situation of the face,the flowing gas model of the face is established.At the same time according to the actually measured data,the quanitity of flowing gas is calculated.The regression model on the quantity of flowing gas is established by the nonlinear regression theory in the mathematical statistics.
