Abstract
Taking the two- period IKONOS2 data acquired in 2011 and 2012 as the information sources,based on the band combination,data fusion and ortho- rectification,the authors made interactive interpretation of the mine geological environment problems,carried out the remote sensing investigation and monitoring work on coal mine environment problems and mine environmental recovery governance of the Juhugeng coal mining area in the Yushania coalfield of Qinghai,combined the mine environment survey results with the geographic and geological data of the mining area,and selected mine geological environment evaluation factors and weight indicators according to the environment condition of the mining area. The dynamic evaluation was conducted for the quality of mine geological environment. The results show that the mine geological environment quality of the Juhugeng coal mining area exhibits a downward trend,the area that affected the mine geological environment by mining activities in 2012 increased by nearly 10 km2 as compared with that in 2011,the vegetation was destroyed directly or indirectly,and the process of the work to control mine recovery couldn't keep up with the process of mine environmental degradation.
