Pasminco Century Mine Open Pit Slope Design — A

The geotechnical factors controlling the design of the open pit slopes of the Pasminco Century Mine near Lawn Hill, Queensland are presented below. Pasminco Century is a stratiform shale hosted zinc deposit in the Lawn Hill Formation that is overlain in part by the Thorntonia Limestone Formation. Both the mineralisation and overburden is located within...

SLOPE STABILITY ANALYSIS FOR OPEN PITS 1

Analyses of a deep wall in an open pit mine in the Peruvian Andes are used to compare limit equilibrium methods (SLIDE) with distinct element methods (UDEC) when the stability is controlled by rock mass strength. The pit wall has an overall slope angle of 37º and a

Rock slope stability assessment through rock mass

The selection of the blast damage zone thickness T for the Hoek-Brown (HB) criterion is significant in open pit slope design and stability analysis. Traditional slope stability analysis adopts a single value of blast damage factor D for the entire rock mass, leading to the underestimation of slope
