ABSTRACT

Underground topographic support works determine the fulfilling of underground
economical objectives; consequently there is a strong connection between the quality of
topographical works and the quality of mining works, as follows:

- Setting up topographical documentation necessary for projecting these
objectives;
- Executing the planned survey works.

In order to fulfil the underground network works under proper conditions, an important
role is played by the support networks that use their own reference systems, or the
national cartographic system. So, a support network can be defined as the totality of the
materialized topographical points that match the foreseen purpose, with a well
determined position, with a satisfactory precision necessary for land surveying,
conducting underground survey works and setting up all the necessary underground and
surface works directly connected. Taking into account their location in space,
topographical support networks can be of surface or in the underground. The need for
setting up support networks comes from their primary purpose that is creating a unitary
land surveying and conducting underground works together with a unitary graphical
representation. This allows homogenous spatial correlations in accordance with the
requirements of the underground mining works.
The present work concerns with the most important issues in setting up the underground
support networks.

Keywords: topographic support networks, groups of strengths, underground surveying.
