| 摘 要： | 根据矿区控制测量的特点，在矿区水准网基础上，用水准测量的方法联测数量足够、分布均匀的GPS点，然后用GPS高程拟合的方法确定其余大量GPS点的高程，建立矿区GPS高程控制网。结合实例论述了该拟合方法建立矿区GPS高程控制网的精度和可靠性，并分析了它的应用价值。

| Abstract: | According to specialty of mining area control surveying, based on mining area leveling network, use leveling tie-in enough number, evenly distributed GPS points, then use GPS elevation fitting to determine elevation for the rest GPS points and establish a mining area vertical control network. The paper incorporated with living examples to discuss the fitting accuracy and dependability of the mining area vertical control network and analyzed its applied value as well. |
