Recovery of Broken Ore Stocks Left on the Mine Floor and Other Applications of the Underground Mobile Supersucker
Use of conventional LHD units and scrapers on an uneven floor underground leaves behind a significant portion of metal (or precious stones) contained in the already broken ore stocks. Depending on the mining method, this material is often never recovered (ie it is wasted) when utilising conventional mining methods and equipment. The portion of metal or precious stones contained in the conventionally unrecoverable' floor material is included in the initial Ore Reserves estimate when a mining project is being evaluated and capital funds are sought for its development. The application of a Mobile Supersucker, a powerful vacuum cleaner previously not available in Australia, has permitted development of a floor material recovery system. This enables cost effective reclamation of the conventionally' unrecoverable material, allowing for significant additional revenue and enhancement of the return on invested capital. This paper describes the construction of the Mobile Supersucker and outlines the challenges faced during the development of the floor material recovery system and presents physical and financial results achieved on gold and nickel mines in Australia over the last few years. Other applications of the Mobile Supersucker include an alternative hoisting system for underground deposits, underground exploration winzing, mining of narrow and ultra-narrow veins and surface sump clean-down are also outlined briefly.
