摘　　要：以刘庄矿为例,通过对矿区首采面地表移动观测站进行GPS控制网测量以及外业数据的初步处理,实现了对GPS网的重复边检核、同步环闭合差检核和异步环闭合差检核,提高了GPS外业测量的精度和效率,确保了外业成果的可靠性,为内业数据处理提供了可靠的依据,并为今后各期刘庄矿区地表移动观测站测量提供了技术保证,实现了效益和精度的提高。Taking he LiuZhuang mine as an example, GPS control network is used for the first face of the surface mobile observation station measurement and field surveying data primary processing. The GPS network of the repetition the control, the synchronized link closure control and the asynchronous link closure control are redlized, the GPS field measurement accuracy and efficiency are remproved. The reliability of the results is ensured, and a reliable basis is provided for the data-processing.
