Abstract

The invention discloses a high-temperature loose coal-induced inflammable and explosive gas explosion coupling test apparatus and a method thereof. The apparatus comprises a coal reactor, a heating temperature control subsystem, a gas distribution subsystem, a data acquisition subsystem and a host computer. The method comprises the following steps: 1, charging experimental coal particles, and examining the air tightness of the coal reactor; 2, determining the vacuum state of a vacuum gas bottle; 3, carrying out high temperature heating and high temperature monitoring on loose coal; 4, proportioning high-temperature loose coal, and adjusting the pressure balance of the coal reactor; 5, acquiring and transmitting high-temperature loose coal-induced inflammable and explosive gas explosion coupling data; and 6, analyzing and storing the high-temperature loose coal-induced inflammable and explosive gas explosion coupling data. The apparatus and the method can be used to accurately test the mutual promotion relationship between the inflammable and explosive gas and the explosion of the high-temperature loose coal, can be reused to determine the evolution rules of all parameters under various conditions, and are of great significance to the prevention and control of mine coal fire thermo-motive disasters.

Description

technical field [0001] The invention belongs to the technical field of combustible gas explosion induced by loose coal, in particular to a coupling test device and method for combustible and explosive gas explosion induced by high-temperature loose coal. Background technique [0002] In recent years, with the continuous advancement of coal mining technology and technology and the increase in depth, mine thermodynamic disaster accidents have occurred very frequently. Among them, gas explosions and coal spontaneous combustion accidents have strong concealment, inaccurate predictions, difficult governance, and serious consequences. Serious and other salient features. Most of the thermodynamic disasters in coal mines are related to loose coal, and the gas explosion related to loose coal accounts for more than 80% of the deaths. However, when the hidden high-temperature loose coal cannot be completely During oxidation, flammable and explosive gases such as CO, C2H4, and C2H2 wil...
