矿区适宜坐标系的选取是矿区设计中经常遇到的问题。为使矿区平面控制网的坐标系尽可能与国家坐标系统相一致,以便于成果的相互作用。我国现行各种大比例尺测量规范一般规定,测区坐标系统选择时,首先应该考虑采用高斯正形投影统一3°带平面直角坐标系。但是,矿区采用国家统一坐标系统,往往会引起长度变形较大,以至于在测图、用图过程中常常需要加入长度投影改正数,这将给矿区大比例尺测图和工程测量带来不便。在矿区大比例尺测图和工程测量的施工放样中,为避免长度变形过大所带来的繁琐的长度改正,宜采用独立坐标系。本文将从长度综合变形入手,探讨响水矿区的独立坐标系的选取。

The suitable coordinate system＇s selection of mining area being is a question which meets frequently in the mining area design. In order to cause the coordinate system of the mining area plane control net meet with the country coordinates system consistent as far as pos- sible, which is good for the achievement to interact. In each kind of big scale survey standard general requirement in our country, when area coordinates system is choice, using the Gauss conformal projection unification 3~ belt plane rectangular coordinate system is first should consider, when the mining area uses the country unified coordinates system, there will often cause the length to distort in a big way, in the mapping, which needs to join the length projection correction number frequently with the chart process, this will brings inconvenient in the mining area big scale mapping and the engineering survey. In order to avoid this kind of tedious length correction, it is advantageous for the mining area big scale mapping and the engineering survey construction lofting, when the length distorts is oversized, suitably uses the inde- pendent coordinate system. This article will obtain from the length synthesis distortion, to discuss the Xiangshui mining area the coordinate system selection.
