Abstract

The invention discloses a stope mine pressure mechanical simulation test bed that combines analog simulation and physical simulation. The test bed is formed in the way that a simulation mining heighthoisting device, a simulation coal floor rubber plate, a simulation coal seam air sac, a simulation upper roof model block of a layer-shaped structure and a loading air sac are arranged from top to bottom on a cuboid testing frame. The test bed is used for studying the relations between the kinestate of overlaying strata and the change of a coal seam support pressure in the stope advancing process, the relations between the support resistance and the kinestate of the overlaying strata during the weighting of stope, the relations among the kinestate of the overlaying strata, the coal seam support pressure and the distribution of stress on a bottom plate in the stope advancing process, etc.

Description

technical field [0001] The invention relates to a test stand for a mine pressure laboratory in a stope. Background technique [0002] Studying the relationship between the development and change of the stope abutment pressure and the movement of the overlying strata and the relationship between the support and the surrounding rock (roof) at the moment of pressure is the basis for solving the problem of stope pressure and its control. However, due to the complexity of the influencing factors of the development and change of stope abutment pressure and the invisibility of the overlying rock movement in the actual field research, this has brought great difficulties to the theoretical study of stope rock pressure. It is an effective and important way to study rock pressure in stope by using simulation test bench to carry out rock pressure simulation experiment. The traditional mine pressure simulation test bench is to fill in the similar materials of the simulated coal seam and...
