Abstract

The invention discloses a coal-rock seam inclination angle and loading position adjustable similar simulation test rack. The test rack comprises a fixed pedestal (1), and is characterized in that: the platform of the fixed pedestal (1) is equipped with an inclinable frame (3), mobile loading plate vertical slide rails (7) are fixed on the left end and right end of the fixed pedestal (1), sliding blocks are fixed at both ends of a mobile loading plate, and the sliding blocks are mounted in the mobile loading plate vertical slide rails (7). The test rack provided by the invention solves the technical problems of large labor amount, tedious procedure, low safety, single function, large measurement error and the like in similar simulation test stands of the prior art.

Description

technical field [0001] The invention belongs to the rock formation inclination angle and loading simulation experiment technology, in particular to a coal-collecting rock formation inclination angle and a loading position adjustable similar simulation test frame. Background technique [0002] The similar simulation test can complete the research on the laboratory-scale roadway (or tunnel) deformation and failure mechanism, rock layer migration characteristics, and original rock stress monitoring in geotechnical engineering and mining engineering. At present, similar simulation test platforms in China have the following characteristics and disadvantages: [0003] 1) Various similar model materials are used, but most of the test platforms are fixed in size, and it is impossible to load vertically at any position. [0004] 2) The combined form of the overall steel frame is bulky. When building an inclined model, it is necessary to raise the bottom of the test bench to make the...
