摘要
矿区平面坐标系统的建立,目的是为了满足矿区在勘察设计阶段、矿井建设阶段和生产阶段测量精度的要求。本文根据投影长度变形计算公式,对矿区高程面投影变形、以及中央子午线和高程投影面的选择作了详细分析与探讨,论述了选择和建立矿区平面坐标系统的方法。为测绘同行的实际工作提供有益的参考。
the establish of mine lot planar coordinate systems,is to meat cmeasurement accuray at survey and design stage、mine construction stage and production phase.This text on the basis of projection length deformation calculation formula,mine lot elevation surface projective deformation、central meridian and the choice of elevation planes are analyzed in detail,the method of select and establishing mine lot planar coordinate systems,relate and analyze is discussed in order to provide the beneficial reference for surveying and mapping counterparts at practical work.
