The Method Of Mine Geological Environment Assessment Based On GIS And RS In The Different Coal Mine

The unreasonable exploitation and utilization of mineral resources in a long period of time, resulting in the mine geological environment problems. Differences between the complex and geographical region in our country due to geological conditions, mine geological environment problems are more prominent and serious. But the mine geological environment evaluation work has not yet formed a matureheoretical system, and evaluation method has not widely accepted by industry experts. Under this background, the thesis based on the China Geological Survey issued "the Mine Remote Sensing Investigation and monitoring of Beijing-Tianjin region" project, do Mine geological environment evaluation of Fangshan-Mentougou coal mine area and Miyun ore research area using worldview-2data. This research mainly obtains the following results:1.Different research areas have different geological mineralization backgrounds, different minerals, the different mining methods and different development levels, causing a variety of different geological environments on the degree of influence varies, therefore, different study area have to select different evaluation factors.2.The thesis based on multi-source data,chosing WorldView-2and ETM remote sensing image data,and using ARCGIS, ENVI platform,extract the information of each evaluation factor through image pre-processing and image interpretation, and achieved good results.3.The thesis choose different factors of mine geological environment evaluation in different study area. In the study area of Miyun ore tailings chose mine geological disasters as one of evaluation indexes,because of the Tailings has a greater impact on the surrounding geological environment, at the same time, the region has two collapse pits, but the affest is not large, so the mine geological disasters in the region only a level two index. The exploitation is very serious in Mentougou-Fangshan coal mine study area, although the mining has stopped.And the mine geological disaster still exists, and there is an increasing trend, the influence in the region is very big to the mine geological environmen,so regard the mine geological disasters as a class index.3.The evaluation method is proposed for vector polygon with buffer method combined with the previous research method, provide technical support for the development of the mine geological environment evaluation.At the same time,chose AHP with fuzzy mathematics method as the evaluation method of two mines.The method combine the advantage of AHP with fuzzy mathematics method,make a More objective result,and the result procve that the method can be used in the two mines,and get a good effect.4.Mentougou-Fangshan coal mine area and Miyun ore minerals study area, has two different Minerals,different mining in the ways, different natural conditions.The thesis do a comparative study on the evaluation method, evaluation model and evaluation index. By comparing the advantages and disadvantages of various evaluation methods and evaluation model, select suitable methods, models and evaluation...
