Methods of Determination of a Point where a Gallery Breaks Through a Deposit

The problems of underground mining are based on the realization of a stable and precise underground topographic base made under optimum conditions, fulfilling the required conditions can be solved using the vector methods presented in Chapter 6, solving based on analytical, trigonometric and graphical processes. The introduction of an information system for solving the problems of mine penetration in the conditions of using a spatial reference system in optimal conditions of realization of the underground topographic networks of support represents an important contribution in the selection, programming and determination of elements of breaking of mining works performed in optimal conditions, efficient, accurate and economical.
