This paper introduced the design plan and data treatment method of GPS control survey network for coal mine special railway lines from Guhanshan to Zhaogu No.1 coal mine.In this paper,the author analyzed the measurement accuracy of the control survey network,made a comparison on the height difference accuracy between GPS fitting height and leveling height,pointed out that replacing the level height with fitting height was feasible.Application practices show that the laying out method and the measurement procedure of narrow band network with short-side is simple and easy to use,the whole efficiency is high.
