Streszczenie:

This paper deals with the geotechnical assessment of raise-bore hole stability using empirical and numerical stability analyses for the Victoria Project in Ontario, Canada. The scope of work for this paper presumed the raise bore is to be excavated to a 4,0 m diameter and to an approximate depth of 1860 m. The geotechnical and structural data, along with the interpreted major lithological units from the exploration shaft pilot hole were used to evaluate the rock mass classification parameters for the raise-bore hole.
