Influence factors analysis about gas occurrence of No.22 seam in Xinxing coal mine
Abstract：In order to research the control function of gas occurrence from geological structures in Xinxing coal mine,this paper,which based on gas geology regularity,using the gas occurrence structure control theory,establishes the multiple regression model which relies on factors such as seam thickness,burial depth of coal seams,the nature of the fault,tuff thickness and so on.In addition it obtains a good reasonable results which show that the mathematical model of forecasting results is closer to the actual values.The results of the study indicate that：The burial depth is the major influence factors to gas content of No.22 seam in Xinxing coal mine;the tuff,in the upper of coal bed played a positive role on gas preservation;it is easy to occur coal and gas outburst close to the faults towards NW-NWW.
