METHODOLOGY FOR DETERMINING THE BOUNDARIES OF A QUARRY DURING THE TRANSITION TO UNDERGROUND MINING OF UPLAND DEPOSITS

Аннотация

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 V – volume of rock mass, m3, Д - volume of mined ore mass in the pit гм р.м contour, t, М - operational metals in the pit contour, kg, V – volume of overburden rocks, m3, K - coefficient of э вск вск overburden rocks, K - coefficient of rock mass at different depths of the open pit with the use of graphoanalytic г.м method by using the AutoCAD computer program. KEYWORDS Upland deposit, rock mass, ore, quarry, operational metal, overburden rocks, overburden rocks coefficient, rock mass coefficient, graphoanalytic method, balance reserves, side angle.
