Application Of Low Altitude UAV Remote Sensing In A Bauxite Mine Surveying

Mine measurement is a important way to obtain the data of mining terrain. Because of the restriction of traditional measurement technology, it cannot be real-time response to the true situation and accurate guide subsequent mine production of the wide distribution and bauxite mining area. Using the low-altitude UAV remote sensing technology can provide the DLG, DEM and DOM which is used to realize the digital mine construction. The main purpose of this paper is combining the low-altitude UAV remote sensing system with the requirements of mines surveying and mapping and putting the low-altitude UAV remote sensing system into the actual mine surveying and mapping as well as the production and construction.In this paper the main research contents and results are as follows:(1)According to the low altitude UAV remote sensing system composition and characteristics of combining the feature of a bauxite mine and the requirements of surveying and mapping, analyzed the applicability of the low-altitude UAV remote sensing system in mine surveying.(2)Choosing a bauxite mining area as the research object analyses the application of the low-altitude UAV remote sensing system in the field of surveying and mapping, including the UAV image data acquisition, field as control point layout, aerial triangulation key technology in the industry, DLG, DEM and the production process of DOM, And it also evaluate precision of mathematical precision in DOM.(3)the low-altitude UAV remote sensing system is applied to mine land reclamation of mining area. Getting the DOM by using the low altitude UAV is the basis material of the planning and design of land reclamation which greatly improve the work efficiency of land reclamation. At the same time, the comparative method analyze the superiority of using low-altitude UAV remote sensing system in mines, and it also analyze the benefit of land after the reclamation.The paper is successfully to put the low-altitude UAV remote sensing system into use for bauxite mine survey, and combine it with the practical application, which has achieved good results. By comparing with the technology of traditional measurement, By the use of low-altitude uav remote sensing technology for bauxite mine surveying and mapping,mapping speed, high precision and uniform, low cost, without being limited by the climate and season, surveying and mapping work has been basically achieved from field to target, inthe industry have visual image, at the same time the characteristics of high precision, easy to modify and update. Reduces the cost of surveying and mapping, speed up the surveying and mapping production.
