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

Abstract
Of great importance in the choice of development systems with deep hole stripping is the mutual location of wells and fractures of the ore massif. This significantly affects the cost of 1 ton of extracted ore.According to VNIMI studies conducted at the Kaula mine field of 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: consonant, normal-section and oblique fractures in relation to the Main Tectonic Zone ...
