Abstract
Способ открытой разработки месторождений полезных ископаемых, включающий вскрытие месторождения и отработку полезного ископаемого уступами с формированием наклонных поверхностей откосов уступов и бортов карьера, бурение скважин, заряжание скважин взрывчатыми веществами, отбойку горной массы при взрывании взрывчатых веществ блоками, рассредоточенными по уступам карьера, погрузку и транспортирование горной массы до мест ее складирования или последующей переработки, отличающийся тем, что определяют места расположения и размеры породных блоков, зависающих на откосах уступов, с земной поверхности или площадок вышерасположенных уступов на страховочных канатах опускают рабочих и буровое оборудование к верхней поверхности зависающего породного блока, в зависающем породном блоке пробуривают скважины с расстоянием между скважинами, не превышающим предельного расстояния, равного удвоенной глубине распространения в массив пород в окрестности скважины зоны разрушения пород, возникающей при взрывании в скважине взрывчатых веществ, скважины пробуривают параллельно поверхности откоса уступа, при этом расстояние между скважинами и поверхностью откоса уступа принимают равным глубине распространения в массив пород в окрестности скважины зоны разрушения пород, возникающей при взрывании в скважине взрывчатых веществ.The method of open development of mineral deposits, including opening a field and mining of minerals with ledges with the formation of inclined surfaces of the slopes of the ledges and sides of the quarry, drilling wells, loading wells with explosives, breaking the rock mass when blasting explosives with blocks dispersed over the ledges of the quarry, loading and transportation rock mass to the places of its storage or subsequent processing, characterized in that they determine the location and size of the pore blocks hanging on the escarpment of benches, from the earth's surface or sites of upstream benches on safety ropes lower workers and drilling equipment to the upper surface of the hanging rock block, in the hanging rock block, wells are drilled with a distance between the wells not exceeding the maximum distance equal to twice the depth of distribution into the rock mass in the vicinity of the well of the zone of rock destruction that occurs when explosives are blown in the well, the wells are drilled in parallel the surface of the escarpment of the ledge, while the distance between the wells and the surface of the escarpment of the escarpment is taken equal to the depth of propagation into the rock mass in the vicinity of the well of the rock destruction zone that occurs when explosives are blasted in the well.
