ANALYSIS AND UTILIZATION OF MINERAL PROPERTY CHECKING AND CONTROLLING SURVEY PRECISION OF ANHUI PROVINCE

为了全面落实国务院关于加强地质工作的决定和有关整顿矿业秩序的指示精神,满足安徽省矿业权实地核查需要,在全省约3万km2的矿业权范围内布设D、E级GPS控制点。本次控制测量任务量大、时间紧、精度要求高是前所未有的,本文通过对控制成果质量的精度分析,提出如何利用控制测量成果的一些建议。

To fully carry out the guiding spirit of State Council on strengthening geological work and rectifying the order of mining industry and satisfy the needs of site checking of mineral rights in Anhui Province,GPS control points of D and E class are set up in an area of 30000 square kilometers covered by mineral rights.This controlling survey work is unprecedented for the assignment is heavy,time-pressing and high-precision-required.This paper gave suggestions on how to use and control surveying results through precision analysis of their quality.
