Abstract
The authors have found relationship between stress state and surface roughness of main fracture in rocks: with growth of maximum normal stress in the area of fracture, surface roughness of the maximum normal stress site decreases. Based on the found relationship, the authors propose a method of estimating stress state of a material by value of the material fracture surface roughness.
