在克里沃罗格中部采选公司№1露天矿,当剥岩量最小时,较高的开采强度是保持设计的矿石生产能力的首要条件。采用汽车运输,同时利用倾斜的和水平的采掘带进行台阶开采是该矿实现高强度开采的方法之一。这种方法在№l露天矿的基建和生产中已应用多年。这种方法的要点如下:爆破后,用两台电铲从台阶的上、下平台标高对采区进行采掘。上部(第一台)电铲在采区全宽上采装,按规定的坡度推进。同时,与第一台电铲保有安全距离的下部(第二台)电铲投入
In the middle of Kryvyi Rogo, the company №1 open pit mining company, when stripping the smallest amount of rock, the higher mining strength is to maintain the design of the ore production capacity of the first condition. The use of motor transport, along with bench-top mining with inclined and horizontal mining belts, is one of the ways the mine can achieve high-intensity mining. This method has been used for many years in the infrastructure and production of № l open pit mine. The main points of this method are as follows: After blasting, two electric shovels are used to excavate the mining area from the elevation of the upper and lower platforms of the steps. Upper (first) shovel in mining area full width of the installation, according to the provisions of the gradient. In the meantime, the lower (second) power shovel, which has a safe distance from the first shovel, is put into operation
