Sensing In Dexing Copper Mine Pollution Monitoring And Analysis Applications

Accompanies along with the mine development and environmentalpollution question prominent, how effective monitoring, analysis andcontaminating estimating that the mine brings about, has become thecurrent environment government the most important condition, also is inthe environmental pollution one of most important research contents.Therefore, how thoroughly studies the mine pollution type and its in thespatial distributed pattern and the time evolution rule, the analysis causesthis change the reason, pointed out the mine pollution the influence factor,regarding the plan mine development, the protection environment, theconstruction ecology mine and so on has the extremely important theoryand the practical significance.Along with the remote sensing swift and violent development, it is inthe environmental monitoring, the analysis aspect obtains the importantapplication. This article takes several dozens years mining history DeXing copper mine as to study region, from the mine thermal pollution andthe place thing (vegetation, water, soil) pollutes two aspects to conductthe analysis research. Is hot using ETM infrared high spectrum imagecomes the inversion with the Hyperion to leave De Xing the mining areathermal pollution distribution and the place thing (vegetation, water)pollutes the distribution scope and the pollution intensity information.The research process is:(1) unifies the data message which the ground obtains to analyze the minepollution type, designates the corresponding remote sensing image;(2) leaves the hot island rank spatial distribution using the ETM hotinfrared wave band inversion;(3) mining area hot island distribution analysis;(4) has analyzed the ground actual thing spectrum data, summarizes theirpollution characteristic in the spectrum performance. Provides the theorybasis for the high spectrum image analysis research;(5) carries on the pretreatment to the Hyperion hyperspectral data, andcarries on the radiation adjustment with the FLASSH law to it; (6) withdraws the water body information using the logarithm remnantmethod of difference, attaches according to the mining area water body in600nm(7) the near absorption characteristic difference, disperses a law usingMNF and differentiate the acid water, the alkaline water and the neutralwater scope and the acid and alkali intensity;(8) acts according to the vegetation index, red side index and theabsorption depth withdraws the vegetation pollution information. Finallyestablishes the mining area the spectrum pollution database, will providethe material for later pollution information extraction;This research from the thermal pollution, the thing pollution (water,vegetation, soil) two aspects has carried on the analysis, the research tothe mine pollution. Analyzed for the mine pollution and monitorsproposed the effective method, the method, planned for the minegovernment and reclaims has provided the technology and the knowledgestrut.
