Comparative Evaluation Of Mine Environment Based On Remote Sensing Technology Of Qulong-Jiama Mining Area And Yulong Mining Area

Mining scale increasing makes the mine geological environment problem increasingly prominent.The conventional mine geological environment assessment need to invest a lot of manpower and material resources.Remote sensing technology applied to the evaluation of mine geological environment,which can make the mine geological environment assessment work more efficient,and more scientific and accurate evaluation results.In this paper,based on ARCGIS platform,to drive the Qu Long-Jia Ma mining area and Yu Long mining area as the study area,on the basis of the basic geographic data,geological data and remote sensing investigation interpretation results,mine geological environment assessment subsystem is established.The weights of each evaluation factor given by ahp,finally we drive Qu Long-Jia Ma mining area and Yu Long mining area into good quality area,general quality area and poor quality area and assess two mining area geological environment contrastively.This study has mainly the following results:(1)High resolution satellite data in eastern Tibet overall demand in remote sensing monitoring work in mines.In addition,especially in orthographical correction stage,used the block adjustment method to overcome the lack of control information,based on the PCI environment.(2)The applications of remote sensing and GIS technology to the evaluation of mine geological environment,using the analytic hierarchy process,assigning factor value of each attribute,comprehensively partitioning of mine geological environment quality can comprehensively and objectively evaluate of mine geological environment.(3)Good environmental area of Qu Long-Jia Ma mining area and Yu Long mining area both decreased year by year,poor environmental area increased year by year.2011-2013,good environmental area ratio of Qu Long-Jia Ma mining area and Yu Long mining area is greater than Yu Long,poor environment area ratio is less than Yu Long.2014-2015,good environmental area ratio of Qu Long-Jia Ma mining area and Yu Long mining area is less than Yu Long,poor environment area ratio is greater than Yu Long.The main reason is the mining area of Yu Long is widening.(4)Strip mining for the destruction of land is bigger than underground mining.In mine environmental recovery management work in the future,relevant departments shall focus on open pit mining area,which is more conducive to the environmental recovery control work developing smoothly in the future.
