Rosemont Mine Landforming, Evaluation of Mine Waste Slope Geometry

Summary: 

SWCA Environmental Consultants (SWCA) commissioned Golder Associates, Inc. (Golder) as part of the Environmental Impact Statement (EIS) under preparation by SWCA to determine the feasibility of using mine was te rock material at the proposed Rosemont Copper Project to imp lement landforming approaches.

Golder theoretically evaluated the erosion stability limits of three basic landform geometries (consisting of a planar concave slope, a flow expanding concave slo pe and a flow concentrating concave slope – Figure 4 ) when subject to runoff from the 100 yr 1 hr storm event . This was done to determine if it was feasible to engin eer stable, natural - looking landforms from mine waste materials at the Rosemont site . The principal focus was on preventing excessive erosion . Geotechnical slope stability has not been addressed in this phase of the study
