倾斜条带陡帮剥岩工艺在南芬铁矿中的优化应用
|
摘要
南芬露天铁矿是多分期开采矿山,当前执行的是三期境界向四期境界扩帮过渡。由于四期扩帮区最低作业面距下方三期主采场采剥作业面高差大,过渡时间长,无法保证矿石稳产高产过渡;在上盘通向主采场的原开拓运输道路因扩帮滚石堵塞的情况下,主采场的大部分矿石,必须经由下盘开拓运输系统绕行运输,运距远。针对上述情况,优先在上盘局部扩展1个窄倾斜分条,增加三期采剥区可采矿量,同时在上盘新开辟1条安全可靠、经济合理的临时运输道路,为矿山持续稳产、降低运输成本创造条件。
Nanfen open-pit iron ore is a multi-stage mining mine,and the current implementation is the side slope extension from the third phase to the fourth phase. Because the minimum working surface of the fourth-phase expansion area is far away from the mining and stripping surface of the main mining field in the third-phase,lower stage in height,long transition time cannot guarantee the high-yield and stable transition of the ore. In the case that the original development transportation road leading to the main stope is blocked by the rolling stone caused by the expansion,most of the ore in the main stope must be transported in a long distance through the development transport system at lower plate. In view of the above situation,it is preferred to expand a narrow inclined strip on the upper plate to increase the amount of mining in the third stage. At the same time,a safe and reliable,economical and reasonable temporary transportation road is opened up on the upper plate to create conditions for keeping continuous stable production and lowering transportation cost.
