Description
Technical field
The invention belongs to coal sample combustion simulation measuring technology, particularly underground coal fire comprehensive experimental device.
Background technology
Underground coal fire is a kind of disaster of association Coal Resource Development, and the main coal producer ubiquity in the world is wherein especially serious with Xinjiang, China area coal fire.Xinjiang belongs to arid, semiarid continental climate, and vegetation cover rate is low, and salting of soil, desertification are strong, earth's surface and groundwater resource shortage and skewness weighing apparatus, and desertification area increases year by year, and the ecosystem is very fragile, belongs to typical Oasis Ecological Environment.The natural ecological environment form of Xinjiang region Coal Resource Development association is very severe, and coal fire is one of typical resource-environment-ecological problem.According to update statistics, ended for the end of the year 2008, Xinjiang region is at flame range 49 places, coal-fired field, and wherein 22 places are newly-increased flame range.Flame range area 9.061 × 106m2, annual combustible loss coal resources reach 812.6 ten thousand t, and direct economic loss reaches 1,000,000,000 yuan.
Xinjiang region coal fire point is mainly distributed in the ring Junggar Basin, Tarim Basin, tells the region of alluviation in front of the mountains of breathing out He Yili basin, basin, the regions such as coalfield as southern in standard, accurate eastern coalfield, accurate northern coalfield, Yi Bei coalfield, Yi Nan coalfield, coalfield, Sha Er lake, coalfield, large South Lake, Ta Bei coalfield, coalfield, Wuqia, Ta Xi coalfield and Ta Dong prediction district.These coals taxes are deposited and coal fire distributed areas are predominating path and the supply path of Xinjiang surface drainage system and underground latent water system, are also the upstream regions in Xinjiang Oasis economic zone.Because glacier, Xinjiang, high mountain accumulated snow water source are the main nourishment source of industrial and agricultural production, domestic water, the serious coal fire of association Xinjiang Coal development of resources will certainly cause and have a strong impact on region environment.The major embodiment of the destruction of coal fire to region environment is: the 1. destruction to soil, soil resource and surface vegetation.The same with coal mining, with spreading of coal fire, it is disrumpent feelings that the empty superincumbent stratum that burns can be occurred by the impact of self gravitation, and then cause surface subsidence and cave in.The thermal effect of coal fire also makes flame range and earth's surface, range of influence and country rock temperature thereof raise, the moisture evaporation of soil self-restraint, and the growth conditions of surface vegetation is destroyed, and causes vegetation death; 2. the pollution to earth's surface, groundwater resource and destruction.Due to the thermal effect of coal fire, the heavy metal element meeting enrichment that coal seam and country rock are contained, flame range crack, pores'growth, rainwater, the snow-broth etc. of the flame range of flowing through may be swept along these heavy metal elements to flow into and be infiltrated earth's surface and lithic drainage, thereby causes the pollution to water resource; 3. the pollution to atmospheric environment.The pollution of coal fire to atmospheric environment and destruction have the implication of two aspects, fire smoke to the greenhouse gases of the pollution of low level atmosphere and its release the destruction to atmospheric ozone layer.
The how underground coal fire environmental impact of scientific evaluation, quantitatively disclose the mechanism of action of coal fire on regional environment impact, be the important topic that coal fire research field is needed solution badly, wherein flame range combustion system thermal power characteristic and flame range coal combustion pollutant output, enrichment discipline are the core contents of coal fire environmental impact research.Coal fire burning pollutant output enrichment discipline and flame range combustion system coal combustion working temperature, atmosphere and oxygen supply etc. are closely related, and combustion conditions and burning coal layer ature of coal, the inside and outside heat transfer of flame range, mass transfer are associated.
