摘要
Taking the south Qinshui basin as researching area and the 3# coal bed as the researching target,a geological model of this area was set up on the base of the characteristics of the field stress and the triaxial stress test results of coal samples from Sihe coal mine in Jincheng. The results show that the initiation pressure keeps constant when the maximum horizontal principal stress changes,but increases with the minimum horizontal principal stress increasing,and the variation range is between 10 MPa and 25 MPa. The results coincide well with the field data.This achievement would provide a reference for hydrofracturing design of coalbed methane well in south Qinshui basin.
