Many rock engineering projects show that the growth of tensile cracks is often an important cause disasters, and mechanical behavior rocks essentially transmission, storage, dissipation release energy. To investigate from perspective energy, uniaxial tension tests (UTTs) compression (UCTs) were carried out on three typical (granite, sandstone marble). Different unloading points set before peak stress to separate elastic energy dissipated The input density ut, ue, ud at each point calculated...
Rock drilling machine, INSTRON testing system, and SHPB device are updated to investigate the characteristics of rocks at great depth, with high loads from overburden, tectonic stresses dynamic impacts due blasting boring. It is verified that these systems can be used study mechanical properties rock material under coupled static loading condition give useful guidance for deep mining underground cavern excavation. Various tests determine strength, fragmentation behavior, energy absorption...
Abstract The problem of deformation damage soft rocks and the effect temperature moisture content on mechanical properties has received wide attention in recent decades. To investigate thermal treatment triaxial extension fracture characteristics rock, tests were conducted sandstone specimens with good homogeneity at different heating temperatures ( T = 25, 100, 200, 300, 400, 500, 800 °C) contents K t 0, 20, 50, 80, 100%) help MTS815 testing machine. results showed that: For rock mass...
Red shale is widely distributed among the deep mine areas of Kaiyang Phosphate Mine, which biggest underground phosphate China. Because effect various factors, such as high stress, ground water and so on, trackless transport roadways in were difficult to effectively support for a long time by using traditional supporting design methods. To deal with this problem, some innovative works carried out paper. First, mineral composition microstructure, anisotropic, hydraulic mechanical properties...
