摘要
为了研究王庄煤矿后备区3#煤层的瓦斯赋存特征,采用了瓦斯赋存构造逐级控制理论,结合现场实测资料,研究了地质构造对瓦斯赋存的控制作用以及顶板岩性、煤层埋深、水文地质等因素对瓦斯含量的影响,并建立了多元回归数学模型。结果表明,埋藏深度是影响煤层瓦斯含量的主要因素;瓦斯含量随着煤层埋深的增加而增大。
In order to study the gas deposit features of No. 3 seam in the standby mining block of Wangzhuang Mine, the step by step control theory of the gas deposit structure combined with the site measured information was applied to study the control function of the geological structure to the gas deposit and the roof lithology, seam depth, hydrology and other factors affected to the gas content and to establish a multi element regressive mathematical model. The results showed that the depth would be main factor affected to the seam gas content. The gas content would be increased with the seam depth increased.
