- W2011452788 abstract "In order to further research the expansion of cracks in the rock during hydraulic fracturing, this paper theoretically analyzes the stress state of wall cracks. According to the effective stress criterion of Terzgahi, it gives the mechanical condition of the rock crack expansion. By Moore-coulomb's law, it analyzes the influence of the water pressure in the pores of space wall on the rock fracturing. On this basis, the hydraulic rock fracturing is applied to build physical experiment model of deep mining mine water bursting. By the methodology of combining the analysis of experimental results and theoretical analysis, it analyzes the change of water injection pressure in the hole with rock fracturing and the stress strain relations during rock’s uniform displacement change and loading. The experimental results show that in the process of the water pressure and vertical loading, the increasing fracture load on the rock, constantly produces, expands the cracks and fractures to instability; the mutual influence of water and pressure comes to be the major problem of deep mining rock fracture and mine water bursting." @default.
