REGRESSION ANALYSIS MODEL OF RELATIVE GAS EMISSION RATE OF COALBEDS WITH SAME LEVEL

Based on the theory of mathematical statistics,the regression analysis model between relative gas emission rate(q) and the thickness(H) and breakage degree(B) of coalbeds with same level of -450 m in Xiejiaji No.2 coal mine,Huinan coalfield,is estabished.The work reveals that under the conditions of same geological background and with the same level,the thicker the thickness and the higher the breakage degree of coalbeds,the more the relative gas emission rate.It is believed that the regression analysis is a quantitative method to study gas geology.
