Remote Sensing Monitoring Research of Mine Geological Environment in Southeastern Heilongjiang, China

Southeastern Heilongjiang is abundant in mineral resources, among which coal mine is the most prominent one and is mainly underground mining, which has caused a series of geological environment problems. In order to find out the distribution and hidden dangers of mine geological hazards, land occupation from mining activities and the sources of environmental pollution in the mining area, the environmental investigation and monitoring of mine geological hazards were carried out based on remote sensing technology at Shuangyashan Qitaihe, Jixi and Mudanjiang areas in southeastern Heilongjiang. The main mine geological environment problems in the study area are ground depression, collapse, landslide, debris flow,' land occupation from mining activities, water pollution and solid waste pollution. The environmental investigation and monitoring of mine geological hazards based on remote sensing is obviously feasible. The results can provide decision support services for management departments to deal with sudden and major geological hazards.
