Emergency safety device for isolating mine disaster

Abstract

The invention discloses an emergency safety device for isolating a mine disaster. The device comprises a disaster inducing device, a disaster isolating airbag, an airbag bracket, a high-pressure air pipe and a high-pressure water pipe, wherein the disaster inducing device respectively consists of a steel wire rope, a pulley and a water tank; the disaster isolating airbag consists of an outer high-pressure inflatable airbag and an inner water-filling bag; the inner bag and the outer bag are connected by a steel wire belt; the airbag bracket consists of a top beam and a bracket which are connected by a bearing; the disaster isolating airbag is fixed to the airbag bracket. When the mine disaster occurs, the inducing device is started, the airbag bracket falls down, the high-pressure air pipe and a water pipe valve are opened, high-pressure air in the high-pressure air pipe fills the outer layer of airbag; the outer layer of airbag is expanded, the high-pressure water pipe fills water into the inner bag, the airbag is formed in a tunnel to prevent expansion of a disaster range, and the mine disaster is limited in a limited range. The device provided by the invention has the beneficial effects that the occurrence of the mine disaster can induce start of the device, the range of the mine disaster is reduced, and the device is simple in mounting.

Description

technical field [0001] The invention relates to a mine disaster blocking emergency avoidance device, which is mainly suitable for gas explosion, mine water inrush and local mine fire. Background technique [0002] According to Mei An Zi (1995) No. 50 "Reporting and Statistical Regulations on Worker Casualties in Coal Industry Enterprises", production casualties in the coal industry are divided into the following 8 categories, among which gas explosions, mine water inrush, and fires often cause mass deaths Group injuries. [0003] Gas explosion accidents, such as the gas explosion accident in Hongdong County, Linfen City, Shanxi Province on December 5, 2007, which killed 105 miners; A particularly serious gas explosion accident occurred in the coal mine Haizhou Vertical Shaft, killing 214 people and injuring 30 others. Mine water inrush accidents, such as the Wangjialing mine water inrush accident of Huajin Company on March 28, 2010 caused 153 people to be trapped, 115 peop...

AI Technical Summary

Problems solved by technology

[0008] In order to overcome the deficiencies in the existing mine emergency avoidance devices, the present invention provides a mine disaster blocking emergency avoidance device, which can reduce the impact range of mine disasters and other secondary disasters caused by local disasters in mines, so as to solve the problem of emergency avoidance at present. The cost of dangerous devices and facilities is high, and the disaster personnel are difficult to reach, etc.
