摘要
通过对井下倾斜巷道中三角高程实测资料的精度分析 ,研究用全站仪施测三角高程替代水准测量的可行性 ,解决常规三角高程测量精度偏低的问题。提高了高程测量精度 ,满足了大型贯通工程的需要。
With analyzing the data of the trigonometric leveling under the mine,the anthors have made a research on the trigonometric leveling taking the place of the leveling,resolved the problem of the low accuracy of the routine trigonometric leveling,satisfied the lenge-scale engineering under the mine.
