摘要: 为了研究王庄煤矿后备区3#煤层的瓦斯赋存特征,基于瓦斯赋存对煤矿安全生产的重要性,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,埋藏深度作为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;数学模型的预测值与实际值比较接近,能较好的反映后备区煤层影响因素的实际情况。

Abstract: In order to research the wangzhuang coal reserve area 3 # of coalbed gas occurrence characteristics, based on gas occurrence of the importance of safety production in coal mine, using a gas occurrence tectonic cascade control theory, combined with the measured data, the authors studied geological structures of gas occurrence and control action of coal seam roof lithology, buried depth, hydrology geology factors such as the impact of gas content, and establishes the mathematical model of multiple regression. Results show that the buried depth of coal seam gas content as the main influence factors, Gas content with the buried depth of coal seams increases, Mathematical model of forecasting results and actual values closer can better reflect reserve area of coal seam influence factors of actual situation..

Key words: Gas occurrence, gas content, hydrogeology, multiple regression
