今年6月至9月,有色金属工业总公司航测队在内蒙林西地区进行了1:2.5万高精度航磁试生产,完成了16184测线公里、面积4340平方公里的野外工作。 这次高精度航磁试生产是在有色金属工业总公司地质局的直接领导下,由矿产地质研究院组织进行的,物化探中心齐文秀同志和矿产地质研究院刘东升副院长亲临现场指导。 基线重复飞行资料表明,其磁测精度中误差小于0.8伽码,完全合乎高精度磁测要求。 今年林西地区气象条件不好,飞机及仪器故障也对生产造成了较大影响,在生产过程中曾发生仪器故障19次,但由于航测队的积极检修,使其对生产的影响降到最小,为正常生产创造了条件。
From June to September this year, the non-ferrous metal industry headquarters aviation inspection team carried out 1: 25,000 high-precision aeromagnetic test production in Linxi, Inner Mongolia, completing the field work of 16,184 km2 with an area of 4,340 km2. This high-precision aeromagnetic pilot production was conducted by the Institute of Mineral Geology under the direct leadership of the Geological Bureau of the Non-Ferrous Metals Industry Corporation. Comrade Qi Wenxiu, director of the Geophysical and Geochemical Exploration Center and Vice-President Liu Dongsheng of the Institute of Geology and Mineral Resources came to the site for guidance. Baseline repeat flight data show that the error of its magnetic measurement accuracy of less than 0.8 gamma, in full compliance with high precision magnetic measurement requirements. The meteorological conditions in Linxi are not good this year. Aircraft and equipment failures have also had a big impact on the production. In the production process, equipment failure occurred 19 times. However, due to the overhaul of the aerial survey team, its impact on production was minimized , Created the conditions for normal production.
