Fracture propagation and pore pressure evolution characteristics induced by hydraulic and pneumatic fracturing of coal

Abstract A two-dimensional unsteady seepage model for coal using a finite element program is developed, and the temporal variations of key factors such as water pressure and hydraulic gradient are analyzed in this paper. Additionally, the triaxial rock mechanical experiment and utilized pneumatic fr...
