Influence of ore massif fracturing on ore breaking stripping by deep boreholes at the mines of the Pechenganickel Combine

Abstract
Of great importance in the choice of mining systems with deep hole breaking is the mutual location of boreholes and fractures of the ore massif. This significantly affects the cost of 1 tonne of extracted ore. According to VNIMI studies conducted at the Kaula deposit of the Pechenganickel Combine, and according to the author's observations during the mining of four blocks of horizons 320 and 260 m of this mine, the fracturing of the ore body within the area under consideration is characterized by three systems of fractures: conformable, cross cutting and oblique in relation to the main tectonic zone.
