British Columbia Mine Reclamation Symposium

Resloping of waste dumps : the Bullmoose solution Allen, M. G.


As a result of a review of rock dump reclamation in 2000, resloping of unreclaimed rock dumps from angle of repose to less than a 2:1 slope was adopted as the preferred method. As a result of the analysis and field trials, resloping was performed using two different methods, horizontal cut and incline cut depending upon waste rock dump height. Resloping profiles were designed using three-dimensional modeling software. Productivity of the dozer fleet was analyzed based on dump height, crest length and area reclaimed.
