Numerical simulation analysis of influence of depth on crack turning behavior in hydraulic fracturing of gas-bearing coal seam
As the depth increases, the ratio of horizontal to vertical stress on the coal rock strata will gradually decrease, which affects the crack propagation behavior around hydro-fracture injection hole. In order to explore the characteristics of hydro-fracture crack turning behavior at different depths,...
