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

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.
