摘要
通过变温条件下的煤样渗流实验，探讨了温度、有效应力对煤样渗透系数的影响；根据实验数据，推导出了渗透系数Ｋ和温度ｔ、渗透系数Ｋ和有效应力σ的回归方程，绘出了Ｋ－ｔ、Ｋ－σ关系曲线，并在此基础上推导出了Ｋ和ｔ、σ的综合方程式。
Abstract The affection of temperature and effective stress on pemeability coefficient of Coal Samples are studied through experiments of seepage in coal sample under conditions of variable temperatures.On the basis of the experimental data,the permeabilitu coefficient K and temperature t ,the regression equation of permeability coefficient K and effective stress σ are abtained and the relationship curves of K-t K-σ are plotted.As a result,a comprehensive dquation is dericed for K,t and σ.
