摘　　要：目前在矿山测绘实践活动中,运用最为广泛的控制测量方式为GNSS静态控制测量,在传统地质测量工作中,控制测量一直都是非常重要的工作步骤,控制点的可靠成果可以有效的保证矿山地质测量过程中各界址点的三维坐标精度,同时可以提高整个测绘区域地质图的精度。控制测量的工作步骤还能有效避免在地质测量过程中因为没有分布均匀和一定数量的野外控制点而引起的误差积累和误差传播,会造成地质测量总体工作成果产生较大误差,因此,需要充分发挥控制测量贯穿在整个地质测量工作过程中的控制作用,提高整个地质测量项目的坐标精确度。鉴于控制测量对于测绘工作的重要性,本文简要分析GNSS静态控制测量和图根控制测量的部分工作开展原理和控制测量成果在地质测量中的应用,从GNSS控制网的网形设计到图根控制测量,促使矿山地质测量工作成果更加精确、可靠。At present,in the practice of mine surveying and mapping,the most widely used control survey method is GNSS static control survey.In the traditional geological survey,control survey has always been a very important work step.The reliable results of control points can effectively ensure the three-dimensional coordinate accuracy of each boundary point in the process of mine geological survey,and improve the accuracy of the geological map of the whole surveying and mapping area.The working steps of control survey can also effectively avoid the error accumulation and error propagation caused by the lack of evenly distributed and a certain number of field control points in the process of geological survey,which will cause large errors in the overall work results of geological survey.Therefore,it is necessary to give full play to the control role of control survey throughout the whole process of geological survey and improve the coordinate accuracy of the whole geological survey project.In view of the importance of control survey for surveying and mapping work,this paper briefly analyzes some work principles of GNSS Static Control Survey and mapping control survey and the application of control survey results in geological survey.From the network shape design of GNSS control network to mapping control survey,the results of mine geological survey work are more accurate and reliable.
