Description
Technical field
The present invention relates to cooling system, relate in particular to a kind of refrigeration cool-down system that is applied to high temperature workplaces such as coal, mining.
Background technology
The colliery is one of main energy sources of China, and along with the development of society and the reinforcement day by day of coal resources exploitation, the mining depth of mine constantly increases.At present, each country of mainly mining of the world enters deep mining in succession, the progressively increase of mining depth, and ground temperature also increases.Oneself reaches 1400 ~ 1500m German and more Muscovite mining degree of depth; The South Africa Ka Lidunweier exploitation of gold deposit degree of depth reaches 3800m, and oneself reaches the following 4146m in the face of land vertical shaft shaft bottom; The mine of the super km of Canada has 30, and the U.S. has 11.China's coal-mine 1980 annual mean mining depths are 288m, have reached 428m to nineteen ninety-five, and present mining depth increases with the speed of 8 ~ 12m every year on average, adopt the dark 1000m of surpassing mine oneself have tens of right.
According to survey data all over the world, whole world mean ground temperature gradient is about 3 ℃/100m, according to national mine elevated temperature heat evil reconnaissance information statistics, heat evil has in various degree appearred in the existing at present 65 pairs of mines of China, and wherein the getting working face temperature of 38 pairs of mines is above 30 ℃.According to China's coalfield ground temperature measurement statistics, hundred meter temperature gradients are 2 ~ 4 ℃/100m, and for example table mountain Ba Kuang mean ground temperature gradient is 3.4 ℃/100m, and the primitive rock temperature of-430m level is 33.2 ~ 33.6 ℃, the temperature of getting working face is at 29 ~ 32 ℃, and the highest oneself reaches 34 ℃.Regulation is made to downhole temperature in countries in the world, and on January 1st, 2005 was played new " safety regulations in coal mine " regulation of enforcement in by China, and mine main getting working face air themperature must not surpass 26 ℃, and the air themperature of electromechanical equipment chamber must not be above 30 ℃.Under the deep mining condition, ground temperature constantly raises, and the harm of heat evil and toxic and harmful, dust also increases day by day.These harm have a strong impact on the efficient of operating worker and their physical and mental health, even cause the generation of some mine serious accidents probably, have brought great threat for the safety in production and the daily management thereof of mine.
The measure of administering underground thermal pollution mainly contains two kinds: a kind of is non-mechanical refrigeration cooling measure, and another kind is to adopt the mechanical refrigeration cooling measure.Dual mode all is on the basis of mine ventilation, makes mine underground work place meteorological condition reach required standard and the cooling measure taked.The former claims the production technique measure again, mainly comprises increasing ventilation, the rational developing of selection and ventilation system, reform draft type, coal winning technology, coal-bed flooding etc., but mainly is meant venting practice; The latter can't reach requirement or the uneconomical measure of taking when reasonable at the former.
Theoretical research and production practices fully show: increase the getting working face air quantity and reduce temperature, improving climatic condition in mine is a kind of both economical effective means, should pay the utmost attention to.But the degree that air quantity increases but is subjected to the constraint of many condition of technology and economy, roadway ventilation section, be subjected to the restriction of the highest permission wind speed, if will keep underground airflow velocity certain, then must enlarge roadway section or roadway quantity, the driving maintenance cost significantly increases thereupon, and the potentiality that continue increase getting working face ventilation are limited, and the heat of down-hole all slatterns, and can not obtain utilizing.
