Monitoring and evaluation of mine geological environment in the Muli coal mining area based on remote sensing

In order to reveal the damage degree of Muli coal mining to the ecological environment, the authors used the 2010 and 2013 two phases of high resolution images of remote sensing monitoring, field investigation, and the soil and water sample collection to investigate mining geo-environmental problems and carrying capacity, The problem was identified and its damage degree and carrying capacity were evaluated. The results show that landform landscape and land resources destruction has been very serious, the water is polluted by Cu, Pb, Cr and Zn, the soil is polluted by Cd and As, the alpine meadow contamination and wetland destruction and degradation are serious, the frozen soil aquifer structure is destroyed, and the mine geological environment bearing capacity is moderate. The evaluation results can provide new basic information for the government and mine enterprises to carry out the recovery management of mine geological environment.
