摘要
从煤层瓦斯渗流的基本方程出发,分析了矿山压力与煤层渗透特征参数的关系;探讨了与煤层回采循环过程相关的时间变量小区间平均离散法;根据加辽金积分方程的弱解表达式,建立了有限元分析的单元特征式。
Based on the govering equation of gas seepage flow,this paper an alyzes;the re-lationship of the underground pressure and permeability of coal seams,discusses the averagedly dis-crete metheds of small terms of time variable which is related to mining progress of coal seams,and set up the element property form ulation on the basis of the weak statement of Galerk in integral e-quation.
