安宁磷矿区基于3S技术的矿山地质灾害隐患三维判识

Three-dimensional Discriminate of Mine Hidden Geological Disaster Based on 3S Technology of Anning Phosphate Area

以云南省安宁磷矿区为例,基于3S技术构建三维模型,在ArcGIS软件中利用高分辨率遥感图像建立矿山地质灾害隐患三维判识标志,圈定并量算出地质灾害隐患体及影响对象的范围,实地了解并验证地质灾害隐患信息的可靠程度,取得的成果为矿山企业和相关管理部门提供了基础信息和决策支持,具有一定的推广应用价值。

With the Anning phosphate mine as the study area and on the basis of the existing interpretation of signs,the high resolution remote sensing images and ArcGIS software were used to delineate and calculate the areas of geological disaster and affected objects and verify the correctness or incorrectness of the information in field.This method is highly feasible and has effective visualization,and the results achieved can provide basic information and decision support for mining business owners and relevant authorities.
