厚表土层矿区高程基准建立与优化

Elevation Datum Establishment and Optimization of Thick Overburden Mining Area

针对厚表土层矿区易沉降变形的状况,提出建立矿区高程控制系统的思路;结合某厚表土层矿区高层基准网建立的实践,阐述了其高程基准网的设计原则,拟定出矿区高程基准网的优化方案,并进行了精度评估。

In view of the condition of the thick overburden mining area that is prone to subsidence defor-mation, the method of establishing the elevation control system of mining area is put forward. Based on an example, this paper expounds the design principle of the altitude control network of the mining areas, draws up the optimization plan, and evaluates the accuracy of the optimization plan.
