Research on nonlinear damage hardening creep model of soft surrounding rock under the stress of deep coal resources mining
To better understand the creep mechanical behavior of deep soft rock coal seam and more accurately predict the long-term deformation of the surrounding rock. Firstly, the electron microscope scanning test under different magnifications and a step loading creep test of deep soft rock were carried. th...
