Abstract

The invention discloses a simulation experiment system and method for simulating coal and rock mass cutting dust production. A cutting experiment device is arranged on the experiment platform; the device is provided with a coal briquette sample, a loading device for loading loads at will, a traction speed loading device, implementation devices of various constraint modes, a roller rotating speed control device, a cutting pick switching device, a mechanical monitoring device and a dust monitoring device, and the experiment system controls all subsystems to complete experiment requirements through a central control system. According to the experimental system disclosed by the invention, simulation analysis on dust produced by cutting of the underground coal mining working face and the tunneling working face can be realized; simulation of dust production caused by cutting damage of different cutting picks under different ground stresses in excavation work can be carried out, mechanical analysis of the cutting picks in the cutting process can be carried out, and research on the influence of different cutting pick types on dust concentration, particle sizes, speeds and microscopic characteristics in the cutting process can be carried out. Theoretical and technical support is provided for dust prevention and control of a mine excavation working face.

Description

technical field [0001] The invention belongs to the technical field of simulation simulation of coal and rock mass cutting dust production, and in particular relates to a simulation experiment system for simulating coal and rock mass cutting dust production. Background technique [0002] At present, my country is the largest coal producer and consumer in the world. This is determined by the resource conditions of rich coal, little gas, and oil shortage in my country. Coal resources are the main energy consumption in my country, accounting for about 10% of the total primary energy consumption. More than 60%. With the continuous improvement of coal mine mechanization and automation, the amount of dust produced in the working space of the mining face continues to increase. The total dust concentration during mining operations can reach up to 3000mg / m 3 ~10000mg / m 3 , in which the dust concentration can reach up to 1500mg / m 3 ~4000mg / m 3 , greatly exceeding the maximum total ...
