A simulation test bench for coal mining work

Abstract

The invention discloses a simulation experiment platform for coal mining work, which comprises: a simulation box filled with simulation materials for simulating the geology of coal-bearing areas; a force generation component I which is arranged on the side of the simulation box and uses is used to exert force on the simulated material from the side of the simulated material; the force generating component II is arranged above the simulated box, and is used to exert force on the simulated material from above the simulated material; the energy release component is two , one of the energy release components is located between the force generation component Ⅰ and the side of the simulation box, and the other energy release component is located between the force generation component Ⅱ and the top of the simulation box, and the simulation When the material exerts a force, the energy release component accepts the force and releases the energy of the energy release component within the simulated material instantaneously, simulating the release of energy during a chemical explosion by means of a physical explosion.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a simulation experiment platform for coal mining work. Background technique [0002] Coal mining is to separate valuable coal from the ground or surface and transport it away from the site. Usually, large-scale mechanical equipment is used for coal mining. There are two types of mining methods: open-pit mining and underground mining. The open-pit mining method is generally from the top. The underground mining directly digs the mine into the coal-bearing seam, in short, it is concentrated mining from above the coal-bearing seam, and the underground mining is to go deep into the coal-bearing seam, adopting the longwall coal mining method, in short, it is Concentrated mining is carried out from the side of the coal-bearing seam. [0003] The movement law of rock strata in coal mining, the law of pressure relief of coal seam, and the law of surface subsidence have always been im...

AI Technical Summary

Problems solved by technology

[0005] 1. The test device has high requirements for the tools used in conjunction with it, and the tools must generate sufficient force to act on the simulated material;

[0006] 2. The test device uses a vibrating machine for continuous gouging, which is easy to damage the geology, increases the difficulty of digging, and is not conducive to the next step of mining;

[0007] 3. The test device will vibrate during continuous gouging, which is prone to the phenomenon that the gouging is not in place;

[0008] 4. The test device does not have the function of simulating blasting coal mining. If explosives are directly used for experiments, the chemical explosion method of explosives is very dangerous, and the use of explosives is harsh and the installation requirements are very high. Professionals need to be specially arranged, which does not meet the requirements of simulation experiments. Timeliness and repeatability, for this we provide a simulation test bench for coal mining
