Close-range photogrammetry technology in mine geological disaster control project acceptance

Mine geological disaster control project is an important work with billions of investment every year in China, but means to acceptance are limited. This study discusses the application of close-range photogrammetry in mine geological disaster control project acceptance of hills and mountains, selected Mentougou in Beijing as study area given the whole process of obtaining field surveying image data by fixed-focus SLR cameras and of indoor data processing with lensphoto data processing software and generated three-dimensional model and topographic maps of the study area. Measuring the height and length of terracing ridges through the topographic maps of the study area and comparing with the design data proved excellent completion of the project. The results show that this technology can be used to obtain high-precision topographic maps and indicator data of acceptance and to be a method of land remediation project acceptance.
