Description
Technical field
The invention belongs to mine or other aeration-cooling fields of civilian underground engineering, more particularly to one kind are cold based on thermostat layer
The mine air cooling system and method at water source.
Background technique
The appearance of mine high-temperature heat evil, has severely impacted the development of mining industry, each high-temperature mine country, the world is 90
Just the research of mine cooling technology has been started before year.Into in the 1980s, refrigeration cool-down has become the master of deep mine cooling
Want technological means.It is widely used in deep and middle deep exploitation especially mechanization and has to take refrigeration with Gao Yanwen mine
And dehumidifying.Simplest is using lesser Portable movable refrigerator, and large-scale central refrigerating system becomes increasingly prevalent.
The deep mining region national more than 15 must rely on refrigeration system, and foremost is gold mine of the South Africa as deep as 3.7km.In Europe
There is air-conditioning system in continent in the exploitation of all deep coalmines.
Mo Laoyuelihe gold mine in Brazil in 1915 establishes first underground airconditioning system in the world, establishes on ground
Central refrigerating station.Adopt deep 2000m, country rock temperature 50 C, using piston refrigerator, motor 530kW, refrigerant R-11, system
Cooling capacity is 1744kW, and spray air cooler is installed in ground, cooling air quantity 2300m3Temperature can be cooled to 6 by 30 DEG C by/min
℃；Britain is most to implement the country of air-conditioning technical early in underground in the world, and first, the Nathan Pendleton coal mine of nineteen twenty-three Britain exists
Refrigeration machine is installed in exploiting field, and cooling coal working face is distinguished and admirable.Depth is adopted most earlier than nineteen twenty-four in ladd labor moral (Radlod) coal mine by Germany
968m, 44 DEG C of country rock temperature, a refrigerator is installed on ground, and using piston refrigerator, refrigerant R-11, power of motor is
150kW, refrigerating capacity 581kW, air cooler are installed in underground, can be by 7200m3/ min air quantity temperature drops to 19.5 by 22.5 DEG C
℃.Installation large-scale distinguished and admirable cooling equipment in underground is the Luo Baiergekuang of nineteen fifty-three earliest.Germany shares 32 pairs of mines, has 28 pairs
Mine uses air-conditioning temperature-reducing, and total refrigerating capacity in 1986 reaches 91.4MW, and in September, 1993 is 256MW.Australia is also using refrigeration
System to enter main ventilating shaft air pre-cool, Ai Sa enterprise copper mine establish 25MW refrigeration system can be air
14.6 DEG C are cooled to from 26 DEG C, the cooling velocity of air is 580kg/s, is equivalent to the ice of manufacture 6300t daily.Canadian mine
Well investment huge fund is taken large capacity ventilation and is administered by the way of Refrigeration Technique.Kai Dekuang takes 21,000,000 Canadian dollars peace
It has filled the refrigeration system of 12MW and has upgraded ventilating system, to improve the mal-condition of the 35 DEG C of temperature in the depths 3000m；Lan Rongde mine
For its 2000m, 38 DEG C of condition, it was mounted with the mechanical cooling system of first 5MW of Canada in 2002, throws again within 2004
It provides 6,600,000 Canadian dollars and upgrades to 12MW, and move to earth's surface；Soon 19MW will be upgraded to.The states such as the Soviet Union, Japan open the 1970s
Begin to apply refrigeration cool-down.Now, external mine air conditioner refrigeration scale is increasing, and development is swift and violent.Japanese mine from 1975 to
Total refrigerating capacity reaches 4528MW within 1985.
South Africa has just started large-scale mine centralized air-conditioning the 1960s.Current mine air conditioner refrigerating capacity in the world
Maximum to surely belong to South Africa gold mine, which is assembled with the refrigerator of cooling to mine, and in November, 1985, South Africa gold mine is ice
It is sent into underground, using the dissolving and heat absorbing of ice, with the cooling water in cooling air cooler, refrigerant system capacity reaches 628MW,
Total refrigerating capacity alreadys exceed 500MW within 1988, and average each mine is more than 11.4MW.The Mponeng gold mine in South Africa, buried depth
The temperature of 3.5km reaches 60 DEG C or so.Mine future mining depth is up to 5km depth, and main shaft may extend to 3.2km.Ventilation
By the high-power ventilation blower of earth's surface, air is sent into one or two vertical shafts, guides air circulation.By divulging information and freezing is filled
The use of object is filled out, air themperature is cooled to 32 DEG C or so.Concrete barren rock mixture is cooling before being delivered to goaf with pump,
Refrigeration is played to remaining ore body.
China is started from 1964 using refrigeration cool-down technology.At that time, Fushun Branch of China Coal Research Institute had introduced one
Platform 4F10 type piston water cooler made in CCCP, refrigerating capacity 58kW, in Huainan Kowloon, Gang Kuang has carried out the test of underground partial cooling, together
When, use surface-type and the two kinds of air cooler of fountain.On this basis, by coal academy of sciences Fushun branch, Chang Shakuang
For the units such as smelting research institute in 1967, joint research and development went out the mining air-cooler of JKT-20 type, refrigerating capacity 70kW.1979, Fushun
It is the mining water cooler of 235kW that branch and Wuhan Refrigerator Plant's cooperation research and development, which go out JKT-70 type refrigerating capacity, is used for driving face
Cooling.1984, in the village Xin Wensun, mine established China First underground central air-conditioning system, which is set by Fushun branch
Meter, design refrigerating capacity are 2324kW, and using 4 type centrifugal refrigerating machines of II-JB50 × 0, single machine refrigerating capacity is 581kW.
The mine, since underground excludes condensation heat difficulty, was changed to ground central air conditioning in 1994 in mining depth entrance -800m level
System, the system import Germany WKM2-1900 type screw water cooling machine set and shell-tube type high-low pressure heat exchanger, and with it is domestic
LSLGF2-25 type water cooler combined operating, overall refrigerating effect ability are 5440kW, this is also the ground central refrigerating of first, China
Air-conditioning system.
It increasing sharply with the plant-scale expansion in China and to demand on ore, the depth of mine just quicklys increase,
Underground heat harm is also increasingly severe.In China's underground heat Risk health behavior, the considerations of in terms of cost, past uses always inhuman
Work refrigeration modes are such as added to wind flow, take away more heat；It is right using the original goaf in mine as cooling capacity warehouse
Convenient dead zone can internal water, outside cold wind stream, which enters, when winter makes water-setting build-up ice, and stores cooling capacity；Outside heat when summer
When wind enters, heat occurs with ice and cold rock wall and exchanges, the cooled cooling of air-flow.As underground heat harm is got worse, force
Property artificial cooling mode will also become the certainty of China's deep-well heat-harm control.But compared with foreign countries, the condition in China mine is more
Harsh, the cost of underground heat cooling is the key that determine the technology success.Although individual mines have carried out some Primary Studies,
But the Refrigeration Technique used is mostly traditional mechanical refrigeration mode, and refrigerating efficiency, cold end and the heat in hot end of core component are handed over
Change that efficiency is lower, the cost for causing Mining Geothermics to control remains high, and many common metal mines are difficult to bear.In this, propose
A kind of mine air cooling system based on thermostat layer water source, system composition is simple, easy to use, be greatly reduced mine cooling at
This, is worthy to be popularized.
