ABSTRACT
Geodetic networks used in mining areas must be very accurate especially in situations where access in the underground is via two different locations positioned away from one another. Every place for access in the underground should have a basis for measurements, well determined as position and orientation in relation to the basis used at the other location for access in the underground. This requires that the design of geodetic networks on mining basin surface must find the optimal geometry of the network and the optimal schedule of topographic measurement, so that, the topographical bases that will be used in future for underground works to be well correlated relative to one another. This paper shows how the shape of network and measurement errors affect the results, namely the quality of the topographic bases. The paper also presents methods that can improve the quality of results.
