11. The mining area measurement control network should adopt ()
A. National 3-degree Gaussian plane rectangular coordinate system
B. Inner mining area coordinate system
C. Independent coordinate system
D. Building coordinate system
[Answer] A
[Analysis] A mining area should adopt a unified coordinate and elevation system. In order to facilitate the mutual utilization of measurement results, the National 3-belt Gaussian plane cartes coordinate system should be used as much as possible to form part of the national level control network. Under special circumstances, the mining area coordinate system of any central meridian or average elevation surface of the mining area can be used. When the mining area is less than 50km and there is no possibility of development, an independent coordinate system can be used.
