GPS改变了传统的矿区控制测量方法。在矿区测量中,GPS对简化测量作业过程和降低劳动强度有明显的作用,因此有必要探讨GPS技术在矿区控制测量中的应用。本文介绍了GPS基本的工作原理,结合实践经验从作业标准、控制测量方法、平差计算和高程拟合4个方面论述了如何利用GPS技术在矿区控制测量以及如何对数据进行处理,并在此基础上提出几点提高测绘精度的方法。
GPS has changed the traditional method of control mining. In the mining survey, GPS has a significant effect on simplifying the measurement process and reducing labor intensity, so it is necessary to explore the application of GPS technology in the measurement and control of mining area. This paper introduces the basic working principle of GPS, and discusses how to use GPS technology to control surveying in mining area and how to process data from four aspects of operation standard, control measuring method, adjustment and height fitting in the light of practical experience. Based on the proposed methods to improve the accuracy of surveying and mapping.
