Mechanism and Numerical Simulation of Vertical Fracture Propagation in Composite Coal Rock
Vertical fracture propagation mechanism is important to understand the effect of hydraulic fracturing on the roof of outburst coal seams. In this paper, the differences in physical parameters and in situ stress between an outburst coal seam and its roof strata were compared, and influencing factors...
