Problems solved by technology

These explosion-blocking technologies belong to post-disaster control, which can only control the hazard degree and scope of gas explosion to a certain extent after the disaster occurs, and still cannot prevent the occurrence of secondary gas explosion disasters from the source.

Abstract

The invention provides a CO2/N2 rapid explosion suppression mine thermal power disaster emergency disposal device and method. The device comprises a gas supply system, a regional isolation system, anenvironmental monitoring system, an explosion risk judging system and a control system, wherein the gas supply system comprises a CO2 gasification device arranged on a ground, a nitrogen making machine group arranged underground and a gas transmission pipeline; the regional isolation system comprises a plurality of one-way valves, an air curtain machine and a three-way electromagnetic valve whichare arranged on the gas transmission pipeline in a working face roadway; the environmental monitoring system comprises a plurality of multi-parameter gas sensors arranged on a roof of an underground working face roadway; and the explosion risk judging system comprises an explosion triangle judging instrument. The CO2/N2 rapid explosion suppression mine thermal power disaster emergency disposal device has reasonable design and exquisite structure, can change environmental conditions of a dangerous area before occurrence of a underground secondary disaster, inhibit formation of explosion conditions, and achieve isolation of an explosive disaster dangerous area, so that the safety of rescue personnel is guaranteed to a maximum extent when the disaster is disposed, and secondary explosion damage is avoided.

Description

technical field [0001] The invention relates to the technical field of mine thermodynamic disaster prevention and control, in particular to a CO 2 / N 2 A mine thermodynamic disaster emergency disposal device and method for rapid explosion suppression. Background technique [0002] Mine explosion thermodynamic disaster accidents have the characteristics of strong suddenness, rapid fire development, difficult disaster relief, and easy to cause secondary injury accidents, which will cause a large number of casualties and resource losses. From 2005 to 2014, there were 192 accidents in my country's coal mines in which more than 10 people died, and the death toll was 3,519, of which gas explosions accounted for 42.7% and the death toll accounted for 47.37%. There are a large number of fire areas in high-gas spontaneous combustion mines, not only a large backlog of coal resources and equipment, but also the interaction between explosive gas and coal spontaneous combustion, which ...
