Waste rock deformations were measured on a high altitude dump using survey prisms and inclinometers. Rates of downslope advancement of about 0.2 to 0.5 m/day (70 to 180 m/year) were measured. This waste dump is founded on very thick (greater than 40 m), warm (approximately -0.5oC) ice-rich Read more... about Creep Displacements Induced from Waste Rock Loading
Soil cover systems are routinely used to reduce acid rock drainage (ARD) from mine waste rock dumps and tailings impoundments. A technology for the analysis, design, instrumentation and monitoring of barrier-type (oxygen limiting) and store/release type covers has rapidly developed and the Read more... about The Integrity of Cover Systems - An Update
The management of mine waste dumps has historically been assigned mainly to the on-site mining operations. In recent years, focus has turned to a more scientific approach to waste rock dump management and the auditing of these manmade structures.
