Embodiment Construction

[0025] As shown in Figures 1 and 2, an isolated refuge system includes a support airbag 1, a wall body 2 arranged outside the support airbag 1, a breathing supply body 4 and an inflator 3; the inflation of the inflator 3 The outlet 5 is connected to the inflation inlet 7 of the support airbag 1 through the air supply pipeline 6; under normal circumstances, all parts of the present invention can be integrated in one package, and in case of an emergency, the inflator 3 can be opened quickly, and the support airbag 1 immediately When the wall is propped up, the whole system enters the working state instantly, and then a small environment is formed in the wall 2 . like Image 6 , downhole operators enter the wall body 2 through the escape door 14 . like image 3 , after the downhole operator enters in the wall body 2, he can quickly put on the breathing mask. The exhalation port 8 and the inhalation port 9 of the respiratory supply body 4 of the present invention are successive...

Abstract

The invention belongs to the field of refuge and survival equipment in underground mining industry, in particular relates to a mine isolated escape system. The escape system comprises a support bellow pot (1), a wall body (2) arranged outside the support bellow pot (1), a breath supplying body (4) and an air charging system (3), wherein an air charging outlet (5) of the air charging system (3) isconnected with an air charging inlet (7) of the support bellow pot (1); an expiration port (8) and an intake port (9) of the breath supplying body (4) is respectively and sequentially connected with an mask expiration port (10) and an mask intake port (11) of a respiratory mask positioned in the wall body (2); the breath supplying body (4) comprises a shell (12) and an oxygen generating agent (13) arranged in the shell (12); and an escape door (14) is arranged in the wall body (2). The system has safe and convenient operation, and can be effectively separated from the external environment of the mine disaster occurrence region when mine disaster occurs; and the refuge chamber can provide corresponding life conditions for human bodies.

Description

technical field [0001] The invention belongs to the field of refuge and life-saving equipment for underground mining, in particular to an isolated refuge system for mines. Background technique [0002] At present, there is no special mine refuge and life-saving equipment in China that can accommodate many people and continuously supply oxygen for more than 72 hours. If a mining accident occurs in the mine, a large amount of poisonous gas will often be produced. Gas products that have specific toxic effects on human physiology can basically be divided into three categories: [0003] 1. Asphyxiating or comatose ingredients; [0004] 2. Ingredients that are irritating to sense organs or respiratory organs; [0005] 3. Other abnormally toxic ingredients; [0006] According to the statistics of death in most mining accidents, most of the victims died of inhaling harmful combustion gases such as carbon monoxide. Because the mining tunnels are blocked or submerged, the miners c...
