Abstract
The invention discloses a three-dimensional similar simulation test system and method based on three-dimensional roadway layout, belonging to the field of mining simulation tests. The test system includes a three-dimensional similar simulation test bench, a mining simulation system and a three-dimensional similar simulation test model; Loading device; the mining simulation system is made up of a plurality of side-by-side mining simulation units, and the mining simulation unit is made up of flexible guide rails, sliders and scotch tape; the three-dimensional similar simulation test model is made up of various simulated rock formations, A number of stress sensors are uniformly arranged at equal intervals. The invention solves the problem that the arc section of the working face in the three-dimensional roadway layout is difficult to simulate; it can realize the simulation of the working face with different cutting depths and different mining heights; in order to obtain the accurate three-dimensional roadway layout roof rock layer migration and fracture law and stress The distributed state creates the conditions.
Description
technical field [0001] The invention relates to a three-dimensional similar simulation test system and method based on three-dimensional roadway layout, belonging to the field of mining simulation tests. Background technique [0002] With the depletion of shallow easy-to-mining coal resources, coal resources with complex geological conditions such as deep dips have gradually become the mainstream of mining. In order to solve the problems of strong mine pressure, low coal recovery rate and poor equipment stability under such geological conditions, more and more More and more mines adopt three-dimensional roadway layout, that is, the transportation lane and the air return lane are arranged along the floor and roof of the coal seam respectively, and one end of the working face is gradually lifted from the bottom plate to the roof in a gentle arc, and connected with the air return lane. The shape of the working face under this kind of roadway arrangement is asymmetrical, which l...
