矸石充填巷采相似模拟试验研究

In allusion to the key technology of tunnels filled with gangue, based on the similarity theory, this paper conduct the similarity test of gangue filling，according to the ratio of 1:200. The results show that the deformation and stress of surrounding rock of tunnels filled with gangue is ladder growth along with the increased amount of tunnels. Over all, the deformation and stress distribution have its regularity, it can preferably explain the regularity of deformation of surrounding rock of tunnels and appeared mine pressure. It shows that the technology of tunnels filled with gangue can commendably control the deformation of surrounding rock of tunnels and lessen the stress and it is an effective exploitation.
