... to the modeling results, the characters of the in-situ stresses both of San-hui No.1 mine and K1 coal seam are analyzed. The study shows that by building the geological model from the earth s surface, the influence of terrain on initial in-situ stresses field has been studied; the coal and rock mass in Sanhui...
