Blasted rock mass stockpile management at a quarry
Abstract
Analysis of the Kovdorskiy open pit operation over the last 5 years has shown that the volume of the blasted block varied widely (from 30 to 130 thousand m3), with its average value for rock decreasing by 22.4 thousand m3 (from 55.6 to 33.2 thousand m3) and for ore by 28 thousand m3 (from 51.5 to 23.5 thousand m3). Transient reserves of blasted rock mass also fluctuated significantly; its maximum reserve in 1967-1968 reached 780-800 thousand m3, and in 1969 amounted to 840 thousand m3, while the minimum reserve in 1965 was equal to 270 thousand m3, and in 1967 and 1968 amounted to 520 and 500 thousand m3, respectively.
