摘　　要：控制测量是地质测量中的基础工作,是煤炭勘查地质测量中重要的工作步骤。可靠的控制点成果可以有效保障煤炭勘查后续工作中测点的空间位置,同时可以提高整个测区地质图的精度。相较于传统的控制测量技术,GNSS技术以其自动化、全天候、高精度、高效益、测站间无需通视等显著特点在地勘工程测量作业中发挥着举足轻重的作用。以甘肃省永昌县H探区煤炭勘查为例,分析E级GNSS控制点测量的原理和控制测量工程的实施步骤,通过对数据处理结果的分析,得到可靠的成果资料,从控制网的设计到图根点测量,使煤炭勘查地质测量工作更加可靠、准确。Control survey is the fundamental work in geological survey and an important step in coal exploration geological survey.Reliable control point results can effectively guarantee the spatial position of survey points in the follow-up work of coal exploration,and can improve the accuracy of the geologic map of the whole survey area.Compared to traditional control surveying techniques,GNSS technology plays a crucial role in geological exploration engineering surveying operations thanks to its characteristics of automation,all-weather,high accuracy,high efficiency,and no need for inter station visibility.Taking the coal exploration in H exploration area in Yongchang County,Gansu Province as an example,this paper briefly analyzes the principle of the survey of E-class GNSS control points and the implementation steps of the control survey project.Through the analysis of the data processing results,reliable data are obtained.From the design of the control network to the mapping point survey,the coal exploration geological survey is more reliable and accurate.
