Several Problems About Analyses of Finite Element Method on Coalbed Gas Seepage Flow

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.
