摘　　要：测绘基准是国民经济建设和国防建设的重要基础设施。文章基于测绘基准提出了浅地测绘基准与深地测绘基准的基本概念,从介质折射率与电磁波衰减特性角度分析了电磁波在深地环境与地面环境中的传播差异,指出了深地环境下电磁波测距还缺乏理论依据,总结了近几年千米深矿井长距离贯通导线边测量与高程联系测量方面的方法与技术,并对深地工程测量中存在的工程与科学问题进行探讨,为深地环境下的工程测量提供研究方向与理论基础。The surveying and mapping datum is an important infrastructure for the construction of the national economy and national defense.Based on the surveying and mapping datum,the paper puts forward the basic concept of shallow ground surveying and mapping datum and deep ground surveying and mapping datum.The difference of electromagnetic wave propagation in the deep ground and the ground environment is analyzed from the perspective of the refractive index of the medium and the electromagnetic wave attenuation characteristics which draws the conclusion that the electromagnetic distance measurement under deep ground environment still lacks theoretical basis.The paper summarizes the methods and techniques of long-distance traverse surveying and elevation measurement in the kilometer-deep mine in recent years,and discusses the engineering and scientific problems existing in deep ground engineering survey,providing research direction and theoretical basis for engineering surveying and mapping under deep ground environment.
