Stoping Mining Methods

Apr 03 2017 Cut-and-fill stoping is applicable to the mining of firm ore enclosed within walls one or both of which are weak and heavy. The deposits may be tabular in form dipping at angles steeper than the angle of repose of the broken ore or flatter if scrapers are employed for moving the ore in the ore passes or to wide thick ore bodies or masses.

Mining Free Fulltext Investigation Of Backfilling

Cemented rock fill CRF is commonly used in cut-and-fill stoping operations in underground mining. This allows for the maximum recovery of ore. Backfilling can improve stope stability in underground workings and then improve ground stability of the whole mine site. However backfilling step scenarios vary from site to site. This paper presents the investigation of five different backfilling .
