Abstract

The invention discloses a coal rock gas dynamic disaster simulation device, which comprises a cylinder body assembly, a pressure relief device and a data monitoring system, wherein the cylinder body assembly comprises a piston rod, an upper cover, a piston, a rubber O-shaped ring for the piston, a cylinder body, a lower cover and the rubber O-shaped ring for the lower cover, wherein a square pressure relief opening is formed in the cylinder body; and the pressure relief device comprises an air compressor, a dynamic pneumatic cylinder, a supporting beam, a bracket, a pressure relief plate, a pressure relief opening sealing plate and a square rubber pad. The coal rock gas dynamic disaster simulation device can simulate dynamic disasters under the conditions of high stress, high gas and different surrounding rocks and is more practical in field engineering.

Description

technical field [0001] The invention relates to a coal-rock gas dynamic disaster simulation device and relates to the technical field of coal mine safety. Background technique [0002] Coal-rock gas dynamic disasters: when coal is mined underground, the gas-containing coal or rock suddenly loses stability under the action of high stress and high gas pressure, releases a large amount of energy instantly, damages the roadway or electromechanical equipment, and rapidly changes the air composition of the mine, causing personnel Casualties, and even secondary disasters such as gas explosions are one of the most important disasters that threaten the safe production of coal mines. [0003] With the increase of coal mining depth, in-situ stress and coal seam gas content increase correspondingly, and coal rock gas dynamic disasters become more serious. Because the coal-rock gas dynamic disaster is the sudden release of coal-rock elastic energy and gas energy, it has the characterist...
