Abstract

The invention provides a coal mine underground self-rescue device, which comprises a clothes type inflatable floating body and an air bag connected on the floating body, wherein the floating body is not communicated with the air bag, and the air bag is connected with a vent pipe. The coal mine underground self-rescue device provided by the invention comprises the floating body and the air bag which are not intercommunicated; and when a miner works under the well, the miner can wear the device, once an accident happens, air and oxygen are immediately inflated into the floating body and the air bag respectively, the floating body full of air generates certain buoyancy, and the air bag full of oxygen supplies oxygen to the miner to prevent gas poisoning. The rescue device occupies small volume, is convenient to wear, and can prevent a person from drowning stifling and gas positioning by using the air bag to replace a heavy oxygen tank.

Description

technical field [0001] The invention relates to the field of coal mine lifesaving, in particular to an underground coal mine self-rescue device. Background technique [0002] Coal mining enterprises often have underground accidents, such as collapses and gas explosions, causing water ingress and toxic gases in the tunnels, making the life safety of miners unable to be guaranteed. Equipping underground self-rescue devices can help save precious lives and buy time for rescue. [0003] The use of life jackets can be used after the roadway is flooded to prevent miners from being submerged in water. However, after the roadway is flooded, it will usually be accompanied by gas gushing out. Most of the roadway is submerged, and the breathing space is greatly reduced and filled with gas. Death by drowning, suffocation or gas poisoning. The use of gas masks can solve the problem of gas poisoning, but it cannot solve the problem of personnel drowning and oxygen supply after the flood ...
