露天采场废石剥离,采用硐室定向抛掷爆破,是一项在短时间内即可获得大量剥离方量的有效技术。它不仅可以大大缩短露天采场的采矿准备时间,而且在劳动力方而可以节约3~7倍,在电力消耗方而可以节约6~13倍,成本降低30%,准备工作、技术条件简单,爆破后工作面不受限制,可以充分发挥运搬机械效率等项优越条件。1959年建矿以来,我矿在黑
Open pit mining waste stone stripping, the use of chamber directed throwing blasting, is a short period of time to get a large amount of peel side of the effective technology. It can not only greatly shorten the open pit mining preparation time, but also in the labor side can save 3 to 7 times, in power consumption can save 6 to 13 times, the cost reduced by 30%, preparation, technical conditions simple, blasting After the work surface is not restricted, you can give full play to transport machinery and other advantages of superior efficiency. Since mine construction in 1959, mine has been in the dark
