Application of remote sensing technology in mine environment monitoring in Liaoning Province

The mineral resources are abundant and the degree of exploration is high in Liaoning Province. But parts of mining activities are out of order and mining eco-environment damage is serious, so the quick and efficient means of remote sensing technology becomes inevitable in mining environment monitoring. Through 4 years of monitoring from 2011 to 2014, it is found out that the mineral exploration in the study area has been improved gradually and illegal mining has been decreased effectively. The current situation of mining land occupancy, geological disaster, environment pollution and recovery and program implementation in this study area has been investigated. The area, minerals types and exploitation methods with high occurrence of illegal mining have been summarized and analyzed. According to mining environment assessment, the serious area, heavier area, general area and no impact area have been delineation. The basic data and principle are provided for orderly and efficiently mineral exploration and environment protection in Liaoning Province. In addition, the problems and research orientations are discussed,and some suggestions for future remote sensing works of mine environment monitoring in Liaoning Province are proposed.
