Cemented paste backfill (CPB) technology has been widely used to fill underground mine voids. Loading next Geomechanics of reinforced cemented backfill in an underhand stope at the Lucky Friday Mine, Mullan, Idaho.
Cemented paste backfill (CPB), which is a mix of tailings, water and cement, is subjected to the combined actions of temperature and sulphate during its service life. There is a need to acquire solid knowledge on the coupled effects of temperature and sulphate on the strength of CPBs for a safe, durable and cost-effective design of
Abstract Underhand cut and fill mining methods are used at the Lucky Friday, Stillwater, and Galena mines in the western US involved the USBM and the University of Idaho (Werner 1990, Brackebusch 1994). Geomechanics of reinforced cemented backfill in an underhand stope at the Lucky Friday Mine, Mullan Idaho.
Its importance is that the underhand mining as practised at Lucky Friday (Mine #12 in Table 1) is the first to incorporate paste to mitigate burst damage and the method has been adopted at mines throughout North America such as the Red Lake Mine in Ontario (Mah et al., 2003) and the Stillwater Mine in Montana (Jordan et al., 2003).
