  • The technical specification for ground high precision magnetic survey (DZ/T 0071-93) currently implemented by the geological and mining industry is a good technical regulation, which has laid a good foundation for the large-scale application of high precision magnetic exploration in China.However due to the technical specification made thirty years ago, there are some historical limitations, and many aspects of it are no longer suitable for today's needs. This paper is the author's summary and reflection on the problems that often occur in the application of the technical specification for ground high precision magnetic survey (DZ/T 0071-93) and the shortcomings that seem to exist at this stage, firstly discussing an extremely common error of precision statisticsin the process of the quality evaluation of ground high-precision magnetic exploration, secondly further discussions on some problems and shortcomings of the precision evaluation related to the specification are made, andput forward corresponding suggestions for improvement.These suggestions may not be the best solutions, but it is hoped that the discussion of geophysicists engaged in high-precision magnetic surveycan arouse, and be helpful to the revision of new ground highprecision magnetic survey specification.
