The present invention proposes a simulation method, device and system for coal seam mining. The method includes: fixing a plurality of simulation devices on the test model frame; The control device fixes the lifting adjustment rod of the simulation device; install the side guard plate of the test model frame and lay similar materials on the top of the simulation device, repeat the actions of installing the side guard plate of the test model frame and laying similar materials until the rock formation is laid to the end of the test model frame Upper end; after the rock formation is dry, remove the side guards of the test model frame; when simulating coal seam mining, calculate the number of simulation devices that need to be lowered sequentially according to the coal seam mining width requirements, and reduce the height of the simulation devices sequentially according to the height that needs to be reduced. The invention solves the technical problems that the model is easy to collapse, the simulation result is unreliable and the simulation material is wasted caused by the method of simulating coal seam mining in the prior art.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a coal seam mining simulation method, device and system. Background technique [0002] Similar material simulation test is an important means for the study of rock formation movement in coal mining, which has the advantages of intuitive image, repeatability, low cost, and not affected by the natural environment. It has been widely used in the research of related issues in the field of mining engineering. [0003] At present, the methods of simulating coal seam mining mainly include hacksaw blade (narrow steel strip) cutting the coal seam laid on the model, extracting the pre-laid small-sized wooden slats, using hydraulic bags to fill and discharge liquid or laying hydraulic jacks at the bottom to adjust the liquid pressure, etc. The main disadvantages of these methods are as follows: (1) The cutting thickness and length are not easy to control, and mining continues after the roof collapse...
