Mining with Backfill QueensMineDesignWiki
Mining with backfill is a requirement in the industry as it is an important aspect of many mining methods and is a solution to many rock stability issues When a mine plans to use backfill there are a number of considerations to be made with regards to type of fill, delivery systems and from where the fill will be obtained As the mining industry gains a better understanding of tailings, it is vital that new and improved methods of containment and storage are developed Weir Minerals believes that the dewatering of tailings has a fundamental role to play in this, and continues to push the boundaries of possibilityTailings dewatering Weir Group Mine backfill, and in particular backfill using hydraulic or paste tailings, is now a wellestablished and proven practice within the underground mining industry Notwithstanding mine backfills’ role as part of a forward looking integrated waste management strategy, the application of the technology offers the opportunity to convert resourceMine Backfill Services Paterson Cooke
