Abstract

The invention discloses a heavy-pitch ultra-thick coalbed fully-mechanized caving mining three-dimensional similar material simulation test bed, which solves the problems in the prior art that the two-dimensional similar material for heavy-pitch ultra-thick coalbed is poor in similarity and accuracy. The test bed comprises a test box body, a coalbed mining simulation system, an acoustic transmitting and monitoring system and a stress monitoring system, the coalbed mining simulation system comprises a peristaltic motor and a controller, the peristaltic motor is connected with a metal lock ring on the tail part of a cylindrical medium simulation material in a test box body, a parallelogram jack is respectively formed in a left baffle plate and a right baffle plate of the test box body. By adopting the heavy-pitch ultra-thick coalbed fully-mechanized caving mining three-dimensional similar material simulation test bed, the simulation in a three-dimensional space form can be carried out and is closer to the real situation of the engineering, the moving rule of a overlying strata in the heavy-pitch ultra-thick coalbed fully-mechanized caving mining process, the pressure release rule of a coalbed soleplate and the surface mining settlement rule can be obtained, and theoretical support can be provided for establishing a heavy-pitch ultra-thick coalbed fully-mechanized caving mining technical system.

Description

technical field [0001] The invention relates to the technical field of simulation tests for similar materials in fully mechanized coal seam caving mining, in particular to a three-dimensional similar material simulation test bench for fully mechanized caving in steeply inclined and extra-thick coal seams. Background technique [0002] Steeply inclined coal seams are widely distributed in my country. This type of coal seam has the characteristics of complex occurrence conditions, large number of mines, and difficult mining. In recent years, many serious accidents have occurred. The reason for this situation is that the The appearance of mine pressure and the law of rock formation migration during mining have not been systematically grasped. Among them, the migration law of the overlying strata, the pressure relief law of the coal seam floor, and the mining surface subsidence law in the mining of steeply inclined and extremely thick coal seams are important theoretical basis fo...
