Upgrading and application of the automated digital mine paste filling system
An analysis was conducted on the issues present in the filling system at Tonglushan Cu-Fe Mine,includ-ing low filling concentration,tailings deposition in the feedwell,outdated equipment and instruments,and high pipeline resistance underground.A comprehensive and efficient automated digital mine filling system upgrade plan was proposed.The cost estimate and economic benefit analysis for the upgrade showed an estimated cost of approximately 16.86 million yuan,with a direct reduction in operating and binder costs by 3.113 7 million yuan/a,indicating significant economic benefits.After the upgrade,an industrial trial of paste filling was conducted.The trial results demonstrated that the new paste filling system at Tonglushan Cu-Fe Mine achieved good filling operation indicators,with a filling concentration of 66％-69％,a filling flow rate of 100-120 m3/h,and a 17.8％reduction in unit binder consumption compared to the previous system.This significantly reduced filling costs,improved filling efficiency,enhanced the mining environment,ensured the quality of the fill,and lowered the risk of pipeline blockages and ruptures.The upgrade had a remarkable effect,providing a valuable reference for similar mines.
