【摘要】 南芬露天铁矿是亚洲最大的铁矿石基地之一,已经由山坡露天开采转为凹陷开采,以往的自然排水已经不能满足生产需要,现在坑底的水已经严重影响到爆破、铲装及运输作业。而我矿的水文资料有限,给我矿的水文研究带来很大麻烦,本文应用现有的炮孔内的水文数据,确定目前开沟穿区的单宽流量和渗流浸润线,为排水提供相关数据,确定排水方案。更多还原

【Abstract】 Nanfen Open-pit Iron Mine is one of Asian biggest iron ore bases,it already transferred hollow mining by hillside open-air mining.Former nature draining water already could not realize.Now the pit bottom water seriously affected the demolition,the shovel installs and the transportation work.But the mine hydrological data is limited,It is the big trouble to the mine hydrology study.This article applies in the existing artillery hole the hydrology data to determine at present gutters the Sichuan area single width current capacity and the transfusion line,to provide the correlation data for draining water and determine draining water plan.更多还原
