摘要
Abstract
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.关键词
