Abstract
1. Способ комбинированной разработки крутопадающих рудных тел включающий отработку карьера до проектной глубины с отстройкой борта в предельное положение, отработку придонных и прибортовых запасов руды с применением подземных выработок, транспортировку отбитой руды по подземным выработкам отличающийся тем, что отработку прибортовых запасов руды ведут после выемки придонных запасов камерной системой разработки под защитой комбинированного породно-закладочного массива со стороны карьерного пространства, причем породно-закладочный массив формируют снизу вверх послойно, с чередованием отсыпки породного отвала и заливки твердеющей закладочной смеси образованного пространства между отвалом и бортом карьера на каждом слое.2. Способ по п.1, отличающийся тем, что в вертикальном сечении породному отвалу придают форму равносторонней трапеции, а закладочному массиву - перевернутой равносторонней трапеции.3. Способ по п.1, отличающийся тем, что высоту формируемого комбинированного породно-закладочного массива выбирают из соотношения:;где h- высота комбинированного породно-закладочного массива;m - горизонтальная мощность рудного тела, м;l- длина очистного пространства придонных запасов, м;α - угол падения висячего бока рудного тела, град.;β- угол наклона борта карьера, град.;b- ширина отрабатываемой камеры, расположенной в прибортовом массиве, м;h- высота отработанных придонных запасов, м.1. A method for the combined development of steeply falling ore bodies, including mining the quarry to the design depth with flailing to the limit position, mining the bottom and ore reserves of ore using underground workings, transporting the beaten ore through underground workings, characterized in that the mining of ore reserves is carried out after the extraction of bottom reserves by the development chamber system under the protection of the combined rock-filling array from the quarry side, and the rock-filling assiv formed from the bottom up in layers, with alternating dumping waste dump and fill settable filling mixture formed by the space between the blade and the edge of the pit on each sloe.2. The method according to claim 1, characterized in that in a vertical section the rock dump is shaped like an equilateral trapezoid, and the backfill array - inverted equilateral trapezoid. The method according to claim 1, characterized in that the height of the formed combined rock-filling array is selected from the ratio:; where h is the height of the combined rock-filling array; m is the horizontal thickness of the ore body, m; l is the length of the treatment space of the bottom reserves, m ; α is the angle of incidence of the hanging side of the ore body, degrees; β is the angle of inclination of the pit side, degrees; b is the width of the mined chamber located in the instrument array, m; h is the height of the depleted bottom reserves, m.
