Abstract
The invention discloses a tailing mesh gel foam mud fire prevention and extinguishing agent. The key point of the technical scheme adopted by the invention lies in that the tailing mesh gel foam mud fire prevention and extinguishing agent is composed of a tailing composite flame retardant foaming agent, attapulgite pottery clay powder with an air purifying function, inorganic fiber spray coating cotton, attapulgite clay tailing powder, coal gangue powder, expanded perlite powder, sodium alginate and water. The ingredients of the tailing mesh gel foam mud fire prevention and extinguishing agent are input into a rake type mixing machine to undergo high-speed stirring, thus obtaining the tailing mesh gel foam mud fire prevention and extinguishing agent. The mesh gel foam mud is sprayed to a burning coal layer by an inorganic fiber spray coating machine, thus facilitating generating an integral mesh gel foam mud film in a fire prevention and extinguishing process. The film can always cover and adhere to an ore bed surface to rapidly isolate the burning coal layer from air, prevent coal mine from keeping burning and avoid reburning of the coal layer, thus reaching the purposes of flame retardance and fire prevention and extinguishing. The tailing mesh gel foam mud fire prevention and extinguishing agent is suitable for fire prevention and extinguishing of coal mines, mine operation areas and forests.
Description
Technical field
The present invention relates to fire-prevention extinguishing agent, be specifically related to a kind of mine tailing network gel foam mud fire-prevention extinguishing agent.
Background technology
The advantages such as that mining exploitation has is highly efficient and productive, low consumption, generally apply in a lot of coal productions of China base.But because the mining rate of this coal-mining method is large, goaf leaves over that residual coal is many, and height is large, leak out serious, often there will be the series of problems, particularly fire such as insoluble fire, gas, dust.
Fire foam is divided into chemical foam, air foam, fluoroprotein foam, AFFF and water-resistant foam etc.
China Patent Publication No. CN 102614615A, open day: on 08 01st, 2012, name is called " a kind of for the complex fire foam under coal mine ", " a kind of for the complex fire foam under coal mine; to it is characterized in that: be made up of following raw materials according: major ingredient is that concentration is 40%～60% carbonic hydroammonium or sodium bicarbonate aqueous solution and the concentrated sulfuric acid; to press solute mass ratio 2:1～3:1 and mix; auxiliary material is stabilizing agent and blowing agent, and described supplementary product consumption is major ingredient gross weight 0.1%～2% " disclosed.
The weak point of above-mentioned patent is: although this extinguishing chemical coefficient of foaming can reach 20～200 times, foam stabilization time >=2.5h, but can only make at short notice " noble gas carbon dioxide foaming spreads and be full of its space in flame range; oxygen concentration in flame range is declined rapidly; flame range is suffocated because of anoxic ", can not really accomplish contacting of isolated burning coal layer and air, prevention colliery burns away, avoid coal seam resume combustion, reach the object of fire-retardant and anti-fire extinguishing.Taking carbonic hydroammonium as the main raw material of extinguishing chemical, in fire extinguishing procedure, can discharge a large amount of ammonias, pollute the air of down-hole, be unfavorable for operating personnel's health.
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among mine tailing, and tailings impoundment need to take a large amount of soils.A lot of Tailings Dams exceed the time limit or excess load is used, and even violation operation, makes Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area are caused to serious threat.
Concave-convex clay rod, except containing attapulgite, often contains the mineral such as bentonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate.
Gangue is thrown aside, takies tract, and sulfide in gangue is overflowed or leached can atmosphere pollution, farmland and water body, and hillock also can spontaneous combustion breaking out of fire, or in avalanche in rainy season, silts river up and cause disaster.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of mine tailing network gel foam mud fire-prevention extinguishing agent is provided.
