Abstract: The groud support problem caused by the deep underground excavations with Huainan mine -1 000 m as a typical representative has become more and more prominent. This study aims to obtain the stresses and damage characteristics of the surrounding rock of the roadway under vertical,oblique and parallel conditions of the maximum load direction and the axis of the roadway,and to reveal the conditions under which the surrounding rock of the deep tunnel fails. The test results show that the radial strains around the model arch,sidewalls and bottom slab all exhibit tensile strains,forming annular fractures;under greater axial pressure,shear and tensile damage occurs around the perimeter of the roadway,but the formation of tensile and shear damage zones is not synchronized,and the rate of tensile damage is much greater than the rate of shear rupture,resulting in such discontinuous and alternating annular fracture zones in the surrounding rock mass. The zonal rupture occurring in the straight-walled round-arch roadway is characterized by the presentation of stratified fracture at the side walls,and slip-type fracture at the top and bottom of the arch. The results of the study can provide reference for the support countermeasures and optimization of the roadway surrounding rock under high ground stress in the deep mining.
