Abstract
The invention relates to a method for prevention of explosion accidents in coal mines, in particular to a method for putting out coal dust burning. The method concretely includes the steps that waste jute bags or woven bags or canvas is used as fire putting out tools; after a coal dust burning accident happens, the tools are soaked into water to be fully drenched, then, the drenched tools are unfolded and laid on the coal dust surface which is burning, and next, water is splashed onto the laid tools until the fire is totally put out. With the method, not only can air pollution caused when fire is put out with a traditional method and a large amount of flying coal dust is produced be effectively restrained and will health of coal workers not be influenced, but also the explosion accident caused by mixing of the large amount of flying dust and flame is effectively avoided. The method for putting out fire of coal dust accidents has the advantages of being low in cost, best in effect, fastest, safest and the like.
Description
Technical field
The present invention relates to a kind of method of preventing to occur under coal mine explosion accident, put out method while being specifically related to a kind of coal dust burning.
Technical background
Coal dust is the coal dust of a kind of fine particle of producing in the coal mining process.This coal dust not only contaminated air, to affect the miner healthy, and meet fire while in air, reaching finite concentration and can set off an explosion and cause disaster, be to cause the main cause of secondary cycle blast after mine gas explosion.Thus, coal dust is one of mine five the Nature disasters.
At present, mainly prevent the measure of coal dust producing to have: to water filling in coal seam, at coal-face spray sprinkler, available ventilation etc.After taking above measure, increased significantly workload, also improved thus labour cost.
And after the generation of coal dust pyrophoricity accident, the fire extinguishing processing method of taking is mainly to adopt water or fire extinguisher directly to spray toward the place of coal dust burning, process and cause a large amount of coal dusts to fly upward like this, after the tunnel of down-hole neutralizes burned flame mixing, will cause great dust explosion accident.
" a kind of powder that suppresses coal dust blast on fire " that application number is 201010270231.6, this disclosure of the invention a kind of powder that suppresses coal dust blast on fire that combines with calcium carbonate, latex powder and rapid-curing cutback powder.During use, this powder is got final product with spraying after water mixes, there is the advantages such as good flame retardation effect, strong adhesion.
" a kind of new the method that prevents coal dust explosion under coal mine shaft " that application number is 201010190549.3, this invention is use low pressure atomizing rifle, sprayer to getting working face, conveyer belt and the polyvinyl alcohol water solution that the local spray concentration of deposition coal dust is 0.5% is arranged; Because polyvinyl alcohol is high molecular polymer, vaporific polyvinyl alcohol can bond and adsorbs Coal Dust and drop to rapidly ground, effectively reduces Dust Concentration in air; Even coal dust is air-dry also can hardening and lose explosivity again, thereby effectively thoroughly eliminate airborne coal dust, prevent the generation of down-hole dust explosion accident.
" a kind of effective ways of preventing and treating coal mine gas and coal-dust explosion " that application number is 200710100800.0, this invention is to mix a certain proportion of ozone (O in the intake airflow of coal mine
3), be relative gas burst quantity and the absolute outburst amount according to mine, calculate the ozone (O needed in the unit interval of mine in conjunction with overall ventilation of mines
3) total amount, its standard is to control under coal mine face gas content lower than below 1%, and the local ozone (O that is having personnel to work for a long time
3) content is no more than national standard 0.3mg/m
3, retain certain ozone (O in the underground air of colliery simultaneously
3) concentration, can solve colliery underground air muddiness, the depositing dust sterilizing, increase oxygen content in air, fresh air, make Coal Miners enjoy after rain pure and fresh air as forest, stablize the anxious mood of making an uproar of Coal Miners mood, reduce artificial security incident and occur, the effect such as raise labour productivity, be greatly improved the down-hole condition of labor.
Above-mentioned three patents of invention, in implementation process, need special-purpose correlative protection product and facilities and equipment, have improved virtually cost of production.
Summary of the invention
Purpose of the present invention is exactly to overcome the deficiency of above technology and provide brand-new a kind of coal dust burning to put out method.Specifically comprise: apply discarded gunnysack, woven bag or canvas etc. as Fire extinguisher; After the coal dust pyrophoricity accident occurs, above-mentioned instrument is dipped in water and makes it fully drenched, after then the above-mentioned instrument drenched being spread out and bedding to the coal dust face burnt, then toward splash on the tool-face of bedding water until fire extinguish fully.
The present invention is achieved through the following technical solutions:
Method is put out in a kind of coal dust burning, in technical scheme, comprises the following steps:
1, application tool: gunnysack, woven bag or canvas.
2, implementation method: after the coal dust pyrophoricity accident occurs, above-mentioned instrument is dipped in water and makes it fully drenched, then after drenched above-mentioned instrument being spread out and bedding to the coal dust face burnt, then toward splash on the tool-face of bedding water until fire extinguish fully.
The existing following advantage of the present invention:
1, method step proposed by the invention is simple, easy implements.
2, by implementing the present invention, applied instrument is mainly discarded gunnysack, woven bag or canvas etc., without correlative protection product and the facilities and equipment of any special use, has saved conventional method and need to drop into a large amount of physical resources and financial resources, effectively reduces cost of production.
3, by implementing the present invention, effectively avoid a large amount of dust from flying mix with flame and can cause an explosion accident, realized extinguishing method after the accident generation have the best, the most fast, the characteristics such as the safest.
4, traditional extinguishing method causes a large amount of coal dusts to fly upward, and has strengthened the air pollution of environment space in the underworkings, affects significantly the miner healthy; By implementing the present invention, effectively suppressed a large amount of coal dusts and flown upward, not only energy-conservation but also environmental protection.
The specific embodiment
Below in conjunction with embodiment, method of the present invention is further illustrated.
Method is put out in a kind of coal dust burning, and the specific embodiment is as follows:
1, application tool: gunnysack, woven bag or canvas.
2, implementation method: after the coal dust pyrophoricity accident occurs, above-mentioned instrument is dipped in water and makes it fully drenched, then after drenched above-mentioned instrument being spread out and bedding to the coal dust face burnt, then toward splash on the tool-face of bedding water until fire extinguish fully.
Claims (1)
1. put out method when a coal dust burns, it is characterized in that comprising:
