摘要
从分析矿区控制网际要求的长度变形容许数值入手,确立出适合矿区需要的,统一投影带的范围以及对局部坐标系统的选择和换算问题。这在矿区控制测量实践中有重要的实用价值。
This paper gives the answers of national regulated scope of projection zone and problems of choice and conversion of the partial coordinate system suitable for the needs of mine diggings. It is important and valuable in the practice of control measure in the mine diggings.
