Environmental Optimization in Developmental Technologies of Deposits of Building and Road Breakstone

Abstract

Scientifically and practically substantiated geometric shapes and parameters of spent pits allowing for environmental interests are presented. A geographic orientation
of inoperable sides of breakstone quarries is reliably established based on the results of field expeditions, space remote probing, and environmentalmathematical
modeling; the account for which ensures the accelerated formation and maximal density of forest vegetation. It is recommended, when working-out
the deposits of widespread minerals, to form the pits with a maximal area of unworkable pit edges of the West and North exposures. The area of the pit bottom
should have minimally possible sizes providing the safe operation of the mining-transport equipment at the final stage of open mining.
