Abstract:

Some small mines which located in remote place since they are lack of data of measuring control, and need to establish independent coordinate system to solve correspond measuring issues. Meantime, lots of hanging compass should be used in secondary lanes in medium and small sized mines. This paper is giving a simple and effective method for unifying compass guiding line of independent cordinate system and high precision controlling cordinate.

Key words: indepe ndent cordinate, the consistence of coodinate north and compass north, effect checking
