On the methodology of operational exploration at the Pikalevskoye deposit
Abstract
Operational exploration of limestone at the Pikalevskoye deposit is carried out by drilling of core wells. According to the accepted methodology, first of all, the wells are drilled from the day surface on a square grid of 100X100 and 50x50 meters. The depth of the wells is determined by the depth of occurrence of sandy-clay rocks of the Venevsky horizon. In the future, to clarify the qualitative characteristics of limestone, the network of excavations is condensed to 25X25 meters. Wells on this network are passed after overburdening works from the surface of limestone. The depth of the wells is determined by the thickness of the carbonate strata ...
