ABSTRACT
The paper takes into account the sizes taken from topographical network support and how their accuracies affects achievement of mining penetrations. The main problems are punching shear in situations where the mining works have a spatial arrangement. The analysis relates to the general case of a work punching minimum length between two existing mining space with the peculiarities that may result. This paper presents computational models for the points of intersection of underground works and is considering a review of how the success of meeting of both underground works depends of angles and distances measured underground. Based on the analysis of punching accuracy, it is important to choose the right place of meeting of two works that are digging.

Keywords: measurements, penetrations, errors, accuracy, underground mining works.
