Layout of Water Conveyance and Power Generation System for Pumped-storage Power Station Renovated from Open-Pit Mine
摘要
Abstract
The renovation of abandoned open-pit mines into pumped-storage power stations faces specific challenges including complex mined-out area distribution,soft rock conditions,and the absence of surge chamber arrangement conditions.Taking the Fuxin Haizhou Open-Pit Mine Project as an example,this paper proposes a layout scheme for the water conveyance and power generation system applicable to mine renovation in soft rock areas.The scheme adopts a single vertical shaft layout to precisely avoid mined-out areas,employs a semi-underground powerhouse to circumvent risks of large underground caverns,integrates emergency gates with intake/outlet structures based on existing experiences to eliminate independent gate shafts,and under the condition without surge chambers,controls the water inertia time constant within the allowable range through pipe diameter optimization.Results indicate that the scheme successfully avoids the mined-out area concentration zone at depths of-170 m to-200 m,with Tw=1.91 s and Tws=1.72 s meeting code requirements,and the head loss accounts for only 1.32%of the rated head.关键词
