Description
Technical field
The utility model relates to a kind of cold wind unit, particularly relates to a kind of mining portable cold wind unit.
Background technique
When the air temperature of subsurface environment surpasses 28 ℃, miner's morbidity is obviously risen, begin to occur heatstroke even death by accident when surpassing 30 ℃, according to the incomplete statistics since 1984, according to the incomplete statistics since nineteen eighty-three, hundreds of people Yin Gaowen heatstroke has taken place and has fallen in a swoon in the underground work place in China's coal-mine.New river in Shangdong Province Sun Cunkuang is following higher 1.83 times than normal temperature (being lower than 28 ℃) at the miner's of down-hole high-temperature operation place operation the incidence of disease in (downhole cooling system put into operation before) before 1984,3.61 times of Gao Shida." mine main getting working face air temperature must not surpass 26 ℃ to the 102nd regulation of China's " safety regulations in coal mine ", and the air temperature of dynamo-electric chamber must not be above 30 ℃; The air temperature of getting working face surpasses 30 ℃, when the air temperature of dynamo-electric chamber surpasses 34 ℃, must stop operation ".
China is first big coal country in the world, also is the many countries of high-temperature mine quantity.China's pit mining depth-averaged extends to the deep with the speed of 11m every year.At present, the average mining depth of China coal mine under the unified-allocation system is about 680m, and some pit mining degree of depth has reached 900～1300m.According to incompletely statistics, China surpasses 30 ℃ to coal mine excavation working surface air temperature surplus in the of existing 130 at present, and the mining depth of many mines is below 800m.Show in the gross reserves that China predicts, 73.2% reserves buried depth is arranged below 1000m according to coal resources exploitations and protection of resources data.This shows that mine elevated temperature heat evil is not only present problem demanding prompt solution, and in the long term, it will further be developed the deep coal resources from now on to China and will have strategic importance.
China mine deep elevated temperature heat evil problem is very serious, and especially new well mine construction stage and old well depth portion open up more outstanding.Xuzhou San He point ore deposit for example, the Pan Yi of Huainan Mining Group company, mine mine construction stages such as Pan three ore deposits, all reach 30～35 ℃ elevated temperature heat evil, project progress is affected, the new Sun Cunkuang of river in Shangdong Province Mining Group company-800m level development driving, the Fengcheng is built Xin Kuang-600m level development driving and is run into 31～35 ℃ elevated temperature heat evil problem, ore deposit, the peak-to-peak group company Chinese parasol tree village runs into high-temperature-hot-water at driving face and gushes out, cause the driving face wind-warm syndrome up to 34 ℃, similarly the elevated temperature heat evil is many in addition in China, and the very shortage of China's present mine deep getting working face elevated temperature heat evil control equipment, can't satisfy China's mine deep safety, produce efficiently, the sustainable development of restriction China mining of deep mine needs.
At present, China's main employing of mine elevated temperature heat evil control strengthened the ambient temperature that air flux is improved getting working face, to can not implementing the local or concentrated artificial cooling measure in down-hole with the general employing handpiece Water Chilling Units that venting practice solves, but the handpiece Water Chilling Units volume is big, and the down-hole transportation is installed inconvenient; Cold water pipe laying distance, loss of refrigeration capacity is big; System pipe network is complicated and must be incubated processing, and investment, down-hole construction intensity are all bigger.
