Surface deformation field and fracture propagation mechanism of rock-like specimen with pre-existing fracture
Eastern coalfield goes into deep mining gradually in China. Fracture development rises greatly in surrounding rocks, increasing the difficulty in ground control under increased mining disturbance. In order to reveal failure mechanism of fractured rocks and improve ground control of deep coal mine, t...
