Description
Technical field
The invention provides the comprehensive refrigerating method in a kind of down-hole, belong to down-hole refrigeration field of ventilation equipment.
Background technology
The mine of China's underground mining is in order to meet stable annual production in recent years, mining depth is deepened year by year, along with the increase of the pit mining degree of depth, the temperature of underworkings country rock increases, down-hole is caused to be adopted, the environment temperature of pick work plane and various chamber is also just more and more higher, especially each stope, down-hole and driving face, general temperature is all at 35 DEG C ~ about 45 DEG C, underground labour's operation under such hot environment feels very uncomfortable, just not working at last is also sweat all over the body, it is general that all do not adhere to two or three hours must adjourn or substitution, operating efficiency is very low, be unfavorable for very much the physical and mental health of underground labour, the operating environment of down-hole is improved in the urgent need to comprehensive mechanical cooling measure technology.
Now traditional technology has two kinds, one be arrange on mine earth's surface refrigeration machine produce ice slurry, ice slurry by Cemented filling to down-hole each stope, chamber and heading face, ice slurry be ejected heat absorption melting process in and down-hole generation refrigeration; Two is arrange refrigeration machine to produce ice cube on mine earth's surface, and ice cube is transported to each stope of down-hole, chamber and heading face by mine car, produces refrigeration in ice cube heat absorption melting process in down-hole.Although these two kinds of technology can make down-hole produce refrigeration, but its maximum disadvantage is just to make the increase at double of underground gushing water amount, great difficulty is caused to mine down-hole draining, even sometimes, be can not arrange out, if increase drainage pump, change the facilities such as thicker discharge pipe line, huge investment waste will be caused to mine, or even lose more than gain.
Summary of the invention
The object of the invention is to provide a kind of down-hole comprehensive refrigerating method, and good refrigeration effect, can not increase underground gushing water amount, can control the cost that freezes preferably.
The comprehensive refrigerating method in down-hole of the present invention, by water pump, the water in pond is transported to refrigeration machine as cold-producing medium, refrigeration machine by the water in pond by refrigeration machine the water for cooling freezed in storehouse make cold water, the cold water of generation to be transported to the coiler fan one end under mine by refrigeration machine delivery port by water pipeline by high-pressure hydraulic pump, the coiler fan other end is connected to refrigeration machine by water return pipeline, coiler fan by entering the cold water in it, outside blowing cold air.
The comprehensive refrigerating method in described down-hole, use Water Cooling Technology, refrigeration machine passes through the water suction in pond, and make the water in its whole cycle refrigeration system become cold water with this, and cold water is sent into down-hole, in coiler fan, interchange of heat is carried out with air by cold water, cold wind is blown out by coiler fan, and the waste water used is reclaimed by water return pipeline, because the wastewater temperature reclaimed can lower than the temperature of down-hole normal air, waste water is entered refrigeration machine and is again freezed by water, the energy and the water supply volume of refrigeration machine consumption are saved greatly, highly effective control refrigeration cost, and what be transported to down-hole is the cold wind similar to air oxygen detrition degree, and pass through into, water return pipeline closed conveying, water then can not outflow conduit, overcome the situation using ice slurry to cause a large amount of water burst in down-hole, it also avoid the draining difficulty of down-hole equally, rationally reduce costs, and send cold water to down-hole in real time, coiler fan is made to generate cool breeze, refrigeration is very good.
The comprehensive refrigerating method in described down-hole, the water in pond is the mine groundwater being positioned at mining area surface, according to the water yield and the water temperature of water in pond, constantly in pond, adds mine groundwater, with the water yield in supplementary pond and the temperature reducing water in pond.Use the underground water that mining area oneself is dug out, general water temperature is cooler, and refrigeration machine can be made to obtain better refrigeration; and again turn back in pond recycle with the waste water crossed; water can not be caused to waste, and cost is very low, both environmental protection also greatly reduced cost.
The comprehensive refrigerating method in described down-hole, water pipeline and water return pipeline comprise and send water main pipeline and send water branch pipeline and backwater main pipeline and back-flowing and branched pipeline, mine has stope, chamber and heading face, stope, chamber and heading face are equipped with coiler fan, water main pipeline is sent to be connected refrigeration machine with backwater main pipeline one end, the other end is connected to each coiler fan respectively by sending water branch pipeline and back-flowing and branched pipeline, define closed water flow circuits, the cold water generated by refrigeration machine is by each water pipeline, at coiler fan place, by coiler fan by cold water and air generation interchange of heat, air cooling-down is made to form cold air, and cold air is blown out, flow to stope, chamber and heading face, and pass through water return pipeline, remaining water wasting is recovered to refrigeration machine, after refrigeration machine is freezed again by the underground water in pond, again down-hole is sent to by water pipeline.Make each working position, down-hole supply cold water simultaneously, make each position pushing quantity balanced, what each coiler fan also can be balanced equally exports cool breeze to each position, extremely be conducive to the hot blast of down-hole being extruded and discharging ground by exhaust fan, ensure that the refrigeration machine working time is longer, the refrigeration of down-hole is better, and can ensure that each working position, down-hole circulating chilled water is normal.
The comprehensive refrigerating method in down-hole described in the comprehensive refrigerating method in described down-hole, at heading face, place arranges booster, and the cold air that coiler fan blows out is delivered to heading face.Because heading face is comparatively dark, atmosphere draught-free, and also the heat produced is larger, needs booster to coordinate, and the cold wind that coiler fan blows out is delivered to heading face place, ensures that temperature is reduced.
The comprehensive refrigerating method in described down-hole, coiler fan and booster are respectively explosion-proof type coiler fan with MA safety sign and explosion-proof type booster.
The comprehensive refrigerating method in described down-hole, refrigeration machine is provided with water return outlet, and water return outlet is connected to pond by return pipe, by used for refrigeration machine groundwater reclaim in pond, to reuse.Continued to put back in pond by the water used, effectively can reduce the use amount of water, water is flow back to pond, the water in pond can rely on surface evaporation to reduce the temperature of oneself, greatly reducing the input of refrigeration cost.
The present invention compared with prior art beneficial effect is:
