Problems solved by technology

Through investigation, the current outburst test device still has the following deficiencies: (1) It cannot simulate the outburst process under the coupling conditions of the mining stress field, seepage field, and temperature field; (2) It cannot simulate the excavation at different positions from the working face, Delayed outburst conditions induced by slight inducing factors such as different excavation rates; (3) It is impossible to realize the multi-field visualization of the fracture field on the coal seam surface and the outburst pulverized coal migration track field during the delayed outburst process

Abstract

A multi-field coupling visualized coal and gas outburst delayed test device is suitable for use in laboratories to simulate delayed coal and gas outburst in coal mines. Including the visualization box made of transparent materials, the visualization box is equipped with loading system, air source system, temperature control system, camera system and protruding door system, loading system, gas source system, temperature control system, camera system and protruding door system The door system is respectively connected with the data acquisition and control system. It has a simple structure and is easy to use. It realizes the whole-process visualization of the box coal seam seepage field, temperature field, surface crack field, and outburst pulverized coal migration track field, laying a foundation for the study of coal and gas outburst disaster-causing characteristics and its prevention and control.

Description

technical field [0001] The invention relates to a coal and gas delayed outburst test device, which is especially suitable for a multi-field coupling visualized coal and gas delayed outburst test device used for underground simulation of coal mines in a laboratory. Background technique [0002] Coal and gas outburst (referred to as outburst) is an extremely complicated mine gas dynamic phenomenon encountered in coal mine production. A large amount of gas gushes out. my country is one of the countries with the most serious coal and gas outburst disasters in the world. At present, there are more than 1,200 pairs of outburst mines. At the same time, with the increase of coal mine mining depth and mining intensity, some mines that had no outburst dynamic disasters or no obvious signs are now It has also gradually emerged, seriously threatening the life safety of underground workers and the normal production of mines. [0003] Delayed outburst of coal and gas (referred to as dela...
