Embodiment Construction

[0010] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. When the mine where the fire occurs is newly built, or the roadway is shallow and short, or the roadway with less mining surface, the method of drilling fire should be adopted: when the fire occurs, first evacuate the personnel, close the air supply and induced draft fan, reduce the oxygen supply, and accurately After analyzing and judging the location and cause of the incident, A. Close the wellhead door 4 and all roadway ventilation holes, B. Immediately drill vertically on the ground closest to the fire area 1, make the drill hole 1 and the working face 2 of the roadway or goaf Connected, C. Inject carbon dioxide gas downward from the drilled hole 1; according to the site conditions, drill holes 1 around it to inject gas, and use the evaporation pressure and heat absorption value of carbon dioxide to cool down, dilute and isolate the air in the fire ar...

Abstract

A method for extinguishing the accident fire in the roadway of mine shaft includes such steps as closing the gate of mint shaft and all blow holes of the roadway, drilling a hole at the position near the fire region, and filling CO2 gas in the roadway via said hole.

Description

technical field [0001] The invention relates to an underground fire extinguishing technique, which is mainly suitable for eliminating hidden fires and open fires in coal mine roadways or goafs. Background technique [0002] Fire is one of the major disasters that often occur during the mining process of coal mines and other mines. It can not only destroy the mine construction facilities, but also cause the gas explosion to collapse the shaft and burn the coal seam, eventually making the man-made construction come to naught. The loss of resources leads to a large loss of human property and property. Therefore, after a fire occurs, rapid fire extinguishing and timely rescue are necessary means to reduce losses and ensure the safety of employees. At present, after a fire occurs in a coal mine roadway, all well doors and ventilation holes are often closed in order to cut off the supply of oxygen in the roadway to achieve fire extinguishing. Obviously, this method takes a long ti...
