Embodiment Construction

[0033] like figure 1 and figure 2 A gas explosion suppression system for coal mine is shown, which includes a gas detection module 1 for detecting methane concentration and oxygen concentration in the upper corner 10 of the coal mining working face and an intrinsically safe explosion-proof control system electrically connected to the gas detection module 1 Valve 2, the intrinsically safe explosion-proof control valve 2 is electrically connected with an inert gas release device 12 for releasing inert gas to the upper corner 10 of the coal mining face to dilute the oxygen concentration and methane concentration, and for preventing the air inlet lane 8 The oxygen in the coal mining face enters the windshield device-6 of the upper corner 10.

[0034] In this embodiment, the method of diluting the oxygen concentration and methane concentration at the upper corner 10 of the coal mining working face is adopted, thereby reducing the oxygen concentration and methane concentration at ...

Abstract

The invention discloses a gas explosion suppression system and method for a coal mine. The system comprises a gas detection module for detecting concentrations of methane and oxygen at the corner of a coal mining working face and an intrinsic safety type anti-explosion control valve electrically connected with the gas detection module. The intrinsic safety type anti-explosion control valve is electrically connected with an inert gas releasing device for releasing inert gases to the corner of the coal mining working face so as to dilute concentrations of methane and oxygen as well as a wind shielding device I for preventing oxygen in an air way from entering into the corner of the coal mining working face. The explosion suppression method comprises the steps of: 1, detection of concentrations of methane and oxygen; 2, judgment of concentrations of methane and oxygen; 3, dilution of methane and oxygen; and 4, emission of diluted methane and oxygen. According to the invention, the work reliability is high, the underground gas explosion suppression purpose is realized, the coal mining safety is improved, the practicality is strong and the using effect is good, and the system and the method are convenient to popularize and apply.

Description

technical field [0001] The invention relates to an explosion suppression system and an explosion suppression method, in particular to a gas explosion suppression system and an explosion suppression method for coal mines. Background technique [0002] my country is the world's largest coal-producing country, and coal accounts for about 70% of my country's primary energy consumption. Therefore, the coal industry is an important basic industry related to the lifeline of my country's national economy. However, the coal industry is one of the industries with the most serious safety production situation in my country. Preventing and controlling the occurrence of major accidents in coal mines and promoting the fundamental improvement of the safety production situation in coal mines have become major issues that need to be solved urgently at the national and government levels. The core task of safety production work. Among all coal mine disasters and accidents, gas accidents are the...
