【Abstract】 The information from China and abroad indicates that in situ stress has remarkable effect on coalbed permeability.From the analyses of the data of laboratory and test,it is found that coal reservoir’s permeability of China have an index relationship to in situ stress.To some extent,this relationship can be used to forecast the permeability of coalbed.更多还原
