Embodiment Construction

[0019] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0020] Such as Figure 1-3 As shown, the high-efficiency fire extinguishing system suitable for high-gas mine shafts includes a carbon dioxide fire extinguishing system in the shaft, a shaft air intake air volume control system, an underground harmful gas treatment system and a mine online monitoring system.

[0021] The carbon dioxide fire extinguishing system in the shaft includes a carbon dioxide storage station 1 and a number of annular carbon dioxide gas outlets 11 arranged on the ground near the mine, and an annular carbon dioxide gas outlet is arranged at a certain distance from top to bottom on the inner wall of the shaft to the horse head door at the bottom of the shaft. The gas outlet 11 and several annular carbon dioxide gas outlets 11 are all connected in parallel with the carbon dioxide storage station 1, and an independent control switch i...

Abstract

The invention discloses a high-efficiency fire extinguishing system applicable to a highly gassy mine shaft and relates to the field of fire extinguishing of mine shafts. The high-efficiency fire extinguishing system comprises a carbon dioxide fire extinguishing system in a shaft, a shaft air inlet quantity control system, a downhole hazardous gas treatment system and an online mine monitoring system. According to the high-efficiency fire extinguishing system disclosed by the invention, in a normal ventilation mode of the highly gassy mine, by utilizing a combination of the carbon dioxide fireextinguishing system in the shaft, a gas drainage system and the online mine monitoring system, fire in the mine shaft and a downhole horsehead can be rapidly and effectively extinguished, and personal safety of the downhole staff in the highly gassy mine and the property safety of the mine are effectively protected.

Description

technical field [0001] The invention relates to the field of mine shaft fire extinguishing, in particular to a high-efficiency fire extinguishing system suitable for high-gas mine shafts. Background technique [0002] From a national perspective, mine shaft fires have the characteristics of a large area of ​​influence, a large number of people involved in danger, and huge safety consequences and property losses. Therefore, the focus of fire management in high-gas mine shafts and at the bottom of the shaft is to prevent fires. Mainly. For fires with open flames in the shaft of high-gas mines and at the horse head gate at the bottom of the shaft, due to the high risk of backwind in the mine, the high wind speed in the shaft, the rapid spread of the fire, the limited fire extinguishing equipment on the job site, the narrow fire extinguishing space, the large depth of the shaft and the existing There are fire extinguishing methods and tools that are difficult to effectively ext...
