According to the change regularity of deformation modulus, combining with the rock mass structure characteristic of region studied, using interpolation method, the deformation modulus of rock mass in 36# adit can be deduced. The average vertical deformation modulus of rock mass during 0-70 zone is 39Gpa, and the horizontal deformation modulus of rock mass is 51. 3GPa in nature stress state and 50.8GPa in engineering load state. The average vertical deformation modulus of rock mass during 70-140 zone is 32. 2Gpa, and the horizontal deformation modulus of rock mass is 41GPa in nature stress state and 42. 6GPa in engineering load state.
