摘　　要：基于CORS-RTK技术的煤矿开采沉陷区域的正常高数据获取是煤矿地面测量工作的重要部分。本文利用煤矿地面GNSS和水准测量数据,采用曲面拟合和多面函数拟合模型构建某煤矿地面开采区域的似大地水准面,旨在解决煤矿开采区域的GNSS-RTK测点正常高计算问题。算例计算表明:该法确定了较高精度的似大地水准面的拟合面,较好满足了煤矿后续工程中的正常高求算。The acquisition of normal height data based on CORS-RTK technology in coal mining subsidence areas is an important part of the ground measurement work.In this paper,the GNSS and leveling data of coal mine ground are used to construct the quasi-geodeid of a coal mine ground mining area by using surface fitting and polyhedral function fitting model.It is intended to solve the problem of normal height calculation of GNSS-RTK measuring points in the coal mining area.The calculation of the example shows that the method determines the fitting surface of the high-precision quasi-geodeid,which satisfies the normal high calculation in the coal mine follow-up project.
