The invention belongs to fireproofing extinguishing materials field, and in particular to a kind of mining fire extinguishing meterial additive and its application.
Background technology
Fire caused by spontaneous combustionof coal seriously endangers the safety in production in colliery.With the world compared with other main coal producers, I
The inferior grade coal of state is more, and the mine scope of spontaneous combustion is wide, quantity is more, is coal spontaneous combustion rate highest country in the world
One of.
At present, the Xinjiang of China, Ningxia, Inner Mongol etc. save the underground coal fire that also there is large area, annual scaling loss coal amount
10000000 tons~13,600,000 tons, economic loss is more than 20,000,000,000 yuan.Substantial amounts of coal resources are not only burnt in coal spontaneous combustion, and produce
Substantial amounts of SO2、CO、CO2Deng toxic and harmful gas, severe contamination environment and the life security for jeopardizing personnel in the pit, while coal is certainly
Combustion can also induce gas, coal-dust explosion, and there is the generation of a lot of such great serious accidents in China, brought to mine huge every year
Big disaster.
For effectively preventing spontaneous combustionof coal, generally prevented at present using nitrogen, retardant, grouting, gel and three-phase froth etc.
Fire-fighting technique.Wherein gel has the advantages that covering performance is good, absorbing and cooling temperature ability is strong, but small with range of scatter, flowing
The shortcoming of poor performance；Three-phase froth has range of scatter wide, the fast advantage of blow-off velocity, but covering performance after its bubble burst
It is poor with absorbing and cooling temperature.
And be in the milk be one of topmost fire extinguishing means in China's coal-mine underground, mud can absorbing and cooling temperature, to coal body also
There is package action, reach the purpose of oxygen barrier, fire extinguishing effect is notable.During grouting fire extinguishing, effect of the concentration of slurry to fire extinguishing
Influence is very big, if improving concentration of slurry, flyash is settled easily in pipeline, the problem of blocking pipeline occur.To solve above-mentioned ask
Topic, this area uses the big ratio of mud (8:1-20:1) this problem is solved.But after this thin mortar is gone into the well, most of ash is with water four
Place's trickling, it is static after again horse back water ash content from not only making mine down-hole buck overflow, and considerably increase mine earthward to arrange
The abrasion of the workload of water, power consumption and water pump.Scattered fine coal dust heap, severe contamination underground work ring are accumulated everywhere in underground
Border.Moreover, while water ash content is lost in from, water from ash, air enters in mortar, causes the large area of carbon granule and oxygen direct
Contact, brings charcoal to glow, the harm of charcoal spontaneous combustion to underground many places.Practice and theoretical proof, the big ratio of mud is defeated to starch filling of going into the well, no
Only effect is poor, and integrated cost is high, and additional work amount is also very big, it is impossible to carry out in mine.
The Compound-colloid fire-fighting that developed recently gets up mainly uses the existing grouting system in colliery, by water and system
Slurry raw material (loess or flyash etc.) is configured to high concentration slurries, and adding thickening suspending agent prevents it from precipitating, then by filling
Pipeline transport is starched to place to use, and adds minimal amount of gelling agent, ignition position is injected after mixing and forms gel, anti-go out is reached
Fire action.The technology has that blow-off velocity is fast, security is good, the low feature of flame range resume combustion.But the additive used at present
There is the shortcomings of cost is high, gelatinization results are poor.
The content of the invention
The technical problem to be solved in the present invention is to provide the mining fire extinguishing meterial additive of one kind and its application, the fire extinguishing material
