Application of the integrated prospecting evaluation system of"sky and deep"in Altun region-A case study of Ayake-Washixianan
The Altyn region is a medium alpine terrain with steep terrain,the altitude is generally more than 2000 me-ters,and the height is more than 300 meters.The high mountain area has deep cutting,the surface is basically without vegetation,and the bedrock is well exposed.For a long time,due to its extremely bad traffic conditions,mineral explora-tion and development have been seriously restricted.The new round of exploration breakthrough action mainly focuses on Kunlun-Altun,and it is imperative to explore green,low-cost and high-efficiency exploration and evaluation techniques for the alpine mountainous areas and blank areas.Under this background,an integrated exploration and evaluation system of"sky,ground and depth"suitable for Altun area has gradually formed.In this system,"sky"refers to the application of remote sensing technology,that is,the pegmatite dikes are identified and interpreted by high definition satellite film com-bined with Google Maps and other image data,and the concentrated distribution area of pegmatite dikes is defined."Sky"refers to the application of UAV technology,that is,the use of aerial photography and 3D modeling to delineate the exten-sion of pegmatite on the surface;"Ground"refers to the application of traditional prospecting methods on the ground,that is,route geological survey,mapping,trough exploration,sampling analysis and other means to conduct ground verification of pegmatic dikes delineated by UAV and delineate ore-bearing pegmatic dikes."Deep"refers to the application of deep drilling means,that is,the use of portable drilling machines to understand the deep extension and grade change of ore-bear-ing pegmatic dimes.The application of the system can accurately lock the prospecting target area,delineate the ore body,and carry out the exploration and evaluation of the mining area,greatly improving the efficiency of prospecting and short-ening the prospecting period,and it is worth being widely used in the Altun area with strong terrain cutting
