Application of remote sensing technology in mine environment monitoring in Liaoning Province
-
摘要: 辽宁省矿产资源丰富,开发程度较高,但部分矿区开发秩序混乱,矿山生态环境破坏严重。通过2011—2014年4 a的矿产资源开发环境遥感监测,基本查明了全省矿产资源开发状况,矿山开发占地、矿区地质灾害、矿山环境污染和矿山环境恢复治理等矿山地质环境问题,以及全省矿产资源开发规划执行情况; 总结分析了辽宁省矿山开发易出现违法开采的区域、矿种和开采方式; 开展了矿山地质环境评价,圈定出矿山开采对矿山地质环境影响严重区、较严重区、一般区和无影响区。监测工作为辽宁省矿产资源有序、高效开发和环境保护提供了基础资料和科学依据,并指出了目前存在的问题和努力的方向,为辽宁省矿山环境遥感监测的下一步工作提出了建议。Abstract: 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.
