冀东含金属成份的水泥石灰石矿深凹露天矿排水案例分析

Metal ingredients contained in jidong cement limestone mine deep sunken open pit mine drainage case analysis

露天矿山随着开采深度加深,采场将逐渐由山坡采场变为凹陷采场,排水方式也相应由自流排水变为机械排水。对唐山冀东水泥股份有限公司石灰石矿山凹陷开采的防洪排水系统进行计算分析,设计采用截水沟自流-泵站上排排水系统,该系统可减轻采场外汇水对采场的影响,从而降低经营费,为类似工程提供了参考,具有重要的工程实用价值。

With the open pit mine mining depth deepened gradually from the slopes of the stope stope stope into depressions, drainage patterns accordingly by the gravity drainage into mechanical drainage. Tangshan Jidong Cement Co., Ltd. mine limestone mining recessed flood drainage system to calculate and analyze, design uses gravity drainage ditches- on pump discharge and drainage system, which can reduce the impact of water on the stope stope foreign exchange, thereby reducing operating costs, provide a reference for similar projects, it has important practical value.
