- W2349975803 abstract "To counter the prevention and control problem of water disaster in deep coal mining,triaxial compression tests were conducted on the rock with different lithological character under different confining pressure and hydraulic pressure. Based on test results,study was made on the confining pressure and hydraulic pressure effect of the rock strength,and the fitting equations of the rock confining pressure effect,the hydraulic pressure effect and the coupling effect were established. This research showed that the strength of the saturated rock and failure rock increased with the increase of confining pressure,the confining pressure effect of the saturated rock strength was in an exponential relationship,the confining pressure effect of failure rock strength was in a linear relationship when hydraulic pressure was 0MPa and the confining pressure effect of failure rock strength was in a logarithmic relationship when hydraulic pressure was 3MPa; the residual strength of rock decreased with the increase of hydraulic pressure,and the hydraulic pressure effect of rock strength was in a negative exponential relationship." @default.
