Outburst box body of coal and gas outburst simulation device

Abstract

The invention discloses an outburst box body of a coal and gas outburst simulation device. The outburst box body of the coal and gas outburst simulation device comprises a square box body with the upper end opened, a box cover is arranged on the square box body, a center hole and a filling material hole are formed in the box cover, piston holes are formed in the front side wall and the rear side wall of the square box body respectively, an outburst opening is formed in the left side wall of the square box body, an inflation hole and a wire hole are formed in the right side all of the square box body, a transverse channel groove and a longitudinal channel groove which are mutually communicated are formed in the inner surface of a bottom board of the square box body, the channel grooves are covered with an inflation panel, ventilation holes are formed in the inflation panel and communicated with the channel grooves, a groove communicated with the inflation hole is formed in the portion, below the inflation hole, of the right side wall of the square box body, the groove is communicated with the channel grooves located at the lower end, and a baffle is arranged on the inner surface of the rear side wall. The outburst box body of the coal and gas outburst simulation device is reasonable in design, simple in structure, easy to obtain, capable of loading pressure in multiple dimensions, even in inflation and capable of enabling outburst parameters to be detected conveniently.

Description

technical field [0001] The invention relates to a box body, in particular to an outburst box body of a coal and gas outburst simulation device. Background technique [0002] Coal and gas outburst simulation tests were carried out earlier in foreign countries. In 1951, В.В. Hodot and others in the former Soviet Union carried out one-dimensional outburst simulation tests for the first time, creating a new method for outburst simulation tests to study outburst mechanisms. Since then, from 1955 to 1991, scholars from the former Soviet Union, Canada, and Japan carried out a series of prominent simulation experiments. [0003] In 1989, Deng Quanfeng and others carried out the first coal and gas outburst simulation test in my country. Since then, Chinese scholars have carried out a large number of coal and gas outburst simulation tests. The main outburst simulation devices are: ①The one-dimensional outburst simulation test device of the Fushun Branch of the General Coal Research I...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned sealing devices for the coal and gas outburst simulation test have completed the outburst test well, the common features of these sealing devices for the outburst simulation test are that they generally have small pressure bearing capacity, small size, and most of them are cylindrical, so that they are only vertically vertical. dimensional loading; the opening of the sealing device protruding opening induces outburst methods, such as detonator blasting and manual opening; due to the small size of the sealing device, the size of the simulated coal sample is small and the monitoring of outburst parameters cannot be carried out, and the quantification of the mechanical parameters of coal and gas outburst cannot be carried out research needs

Secondly, the existing protruding box is inflated directly from the inflation hole to the box, the inflation is not uniform, and the pressure in the box is not uniform
