METHODOLOGY FOR DETERMINING THE BOUNDARIES OF A QUARRY DURING THE TRANSITION TO UNDERGROUND MINING OF UPLAND DEPOSITS
Keywords:
Abstract
The article presents a method for determining rational boundaries during the transition to underground mining of upland deposits, by performing calculations, comparing overburden coefficients and rock mass.
This method is the simplest for determining Vгм – volume of rock mass, m3, Др.м - volume of mined ore mass in the pit contour, t, Мэ - operational metals in the pit contour, kg, Vвск – volume of overburden rocks, m3, Kвск - coefficient of overburden rocks, Kг.м - coefficient of rock mass at different depths of the open pit with the use of graphoanalytic method by using the AutoCAD computer program.
