摘　　要：乌拉根铅锌矿岩体为软~较软岩岩石,露采进入凹陷采坑后,受坑底地下水影响,岩石破碎泥化现象严重,严重限制了新台阶开拓进度,增加了年度采剥计划任务产量完成难度。经过现场调查研究,制定了采坑地下水疏干治理措施,为新台阶开拓创造条件,现场试验研究软岩台阶的开拓方案,优化采剥作业面参数和工艺流程,形成一套较为经济、安全的沉积型软岩采坑开拓方法,以保障矿山的正常采剥生产作业。The Ulagen lead-zinc mine rock mass is soft to relatively soft rock.After open-pit mining enters the concave mining pit,the rock is severely fragmented and mudified due to the influence of groundwater at the bottom of the pit,which seriously limits the progress of new step development and increases the difficulty of completing the annual mining and stripping plan tasks.After on-site investigation and research,measures for dewatering and treating underground water in mining pits have been formulated to create conditions for the development of new steps.On site experiments have been conducted to study the development plan of soft rock steps,optimize the parameters and process flow of mining and stripping operations,and form a relatively economical and safe sedimentary soft rock mining pit development method to ensure the normal mining and stripping production operations of the mine.
