Description
Technical field
The utility model relates to a kind of coal-seam gas (gas) safe delivery system, is specially the safe delivery system of the down-hole coal bed gas (gas) being applied in coal mining.
Background technique
In the normal place of gas density and gas explosion interval range in down-hole coal bed gas (gas) extraction pipeline, permanent or the underground moving extraction system in ground is when adopting wet type extraction pump to carry out extraction, gas density in pipeline is not required, owing to being negative pressure extraction, in general gas can not be leaked to pipe in managing, and only may from managing, enter in pipe by air, thereby reduction gas extraction concentration, especially tight, the coal seam change of the sealing of hole on face etc., caused a large amount of air to be drawn in pipeline, the reduction of the gas density causing.Even if there is naked light can not propagate in pipeline in tunnel, safety does not have significant impact yet.But the residual coal spontaneous in goaf is got angry, coal bed drilling catches fire, will make flame propagation enter gas pumping pipeline, in order to prevent trouble before it happens, the safety measure of strengthening underground gas extraction system, the harm of eliminating two kinds of dissimilar blasts and causing, when carrying out low concentration gas extraction and utilizing, take down-hole catastrophe preventive measure, can be by the Catastrophe controlling occurring at minimum zone.
Difference in China due to the geological condition in each colliery, the content of gas of coal-seam gas (gas) is dynamic change, concentration changes between 0.5%-80%, and the range of explosion that concentration has just entered gas while entering between 5%-16%, so just there is great hidden peril of explosion, once there be burning things which may cause a fire disaster, will cause a chain of blast, cause huge personnel, property loss, especially within nearly 2 years, Guizhou, 2, Shanxi coal mine gas extraction pipeline are blasted, bring huge loss to life, property, so country more and more payes attention to gas pumping pipe safety problem." one through three prevention " that country proposes in gas mining area is the method that adopts first gas pumping to exploit again, solved the safety that gas is exploited in earlier stage; Rescue capsule, refuge chamber are to guarantee after disaster occurs, personnel's existence farthest to be ensured, but only aspect system control, are being a blank.
At present, safe delivery system and the equipment of existing colliery essence type are less, and methods are single outmoded, have following problem in course of conveying:
Thin water smoke can not fundamentally solve hidden danger, has also increased the content of water in tunnel simultaneously, causes draining difficulty.
Refuge chamber and rescue capsule, because span is large, so can not block protection for miner in time at explosion time, avoid disaster to occur; And inner oxygen memory space is less, can only maintain short period and less personnel's lifesaving.
The flame sensor close together of the dusting device of placing in tunnel and the sympathetic detonation intensity of a fire, dusting device action after stain sensor probe.
Sensor is positioned over down-hole, and because environmental conditions is severe, sensor lacks necessary dustproof protective measures, easily stops up and causes misoperation or be failure to actuate.
