Background technology
Because rapid development of economy, also be raising at full speed to the demand of the energy, as being the country of primary raw material with coal, the yield of coal also climbs up and up, so mine safety accidents also causes a tremendous loss of lives again and again.Through the mass data analysis of and casualty on-the-spot, find that the death toll of underground work causes because sucked CO gas after the gas explosion more than 90% to mine disaster.
Lifesaving booth is all arranged under some large-scale mines, as long as gas explosion accident generation front and back personnel in the pit can enter survival capsule smoothly and just can not be in peril of one's life, but accident will take place in the short time at the utmost point when meeting the outstanding situation of gas, if adopt traditional self-rescuer to have no idea to save oneself at short notice at all.
For a long time, the isolation type oxygen self-rescuer service routine generally used of down-hole, mine is comparatively loaded down with trivial details.Usually unload the respirator of wearing earlier, open two bayonet sockets of breather loam cake, take off loam cake, opening valve gate open oxygen is clamped the nose clip on the leather bag with nose, opens the air bag stopper and catches in its mouth leather bag breathing mouth then.At least needed for 90 seconds from receiving the gas early warning to beginning to wear the chemical oxidation self-rescuer under the skilled situation of calmness, at this moment the underground labour also must stop operation, has so also taken valuable escape time.Add the traditional chemical oxygen self-rescuer and must be hand-held or mouth is stung also and made troubles to escape; in case more likely cause its stupor if the shock wave of its generation of gas explosion is very likely fallen down the underground work personnel; at this moment oxygen self-rescuer will break away from the effect that does not reach protection from mouth and nose, finally will be choked to death by carbon monoxide.
We see that from a large amount of fire damp explosion scene data the concentration of its carbon monoxide of fire damp blast back is generally 1～10%, and these data mean, will lose valuable life as long as suck flatly under this environment.We can judge that conventional self-rescue apparatus saving oneself in the fire damp blast process almost cannot so.
Also have some products to adopt firedamp sensor, carbon monoxide transducer, pressure sensor or shock sensor in the hope of reaching the effect of " automatically " now, but these products finally just rest on the paper.Its impracticable reason mainly is:
If 1, firedamp sensor, carbon monoxide transducer are worn to and necessarily require volume little, in light weight on the individuality.But the product response time of these " mini " types reaches 1～2 minute, and sensitivity is differential.
2, the higher imported product of sensitivity its cost an arm and a leg more than thousand yuan, obviously not have the meaning of popularization as the accessory of individuality equipment with such product.
