摘　　要：为了研究新兴煤矿地质构造对瓦斯赋存的控制作用,以瓦斯地质原理为基础,采用瓦斯赋存构造逐级控制理论方法,以煤层厚度、煤层埋藏深度、断层性质和凝灰岩厚度等影响因素为依托,建立了煤层瓦斯与地质影响因素相互关系的多元回归数学模型,并得出与实际值比较接近的预测值.研究结果表明:煤层埋藏深度是影响新兴煤矿22号煤层瓦斯含量的主控因素;上覆凝灰岩对煤层瓦斯保存起到了积极作用;NW-NWW向断层附近容易发生煤与瓦斯动力现象.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.
