Assessment of ease of excavation of surface mines

1998-7-1During 1987 and 1988 several Canadian surface mines were visited or contacted in an attempt to derive data on equipment and geological and mining environments. Resulting from the survey of prior work, field observations and rock mechanics principles, a new classification system was developed, ( Table 2 and 3 Table 3 ).

Review of Cuttability Indices and A New Rockmass

Rock excavation is carried out either by drilling and blasting or using rock-cutting machines like rippers, bucket wheel excavators, surface miners, road headers etc. Economics of mechanised rock excavation by rock-cutting machines largely depends on the achieved production rates. Thus, assessment of the performance (productivity) is important prior to deploying a rock

A study of electric rope shovel digging effort and

Improving the drilling and blasting practice in open-pit mines is one of the ways to enhance the economics of a mining operation. Diggability assessment is currently considered as a way to provide feedback on blast quality; however, there is no universally accepted approach to evaluate diggability. This research focused on the performance monitoring of electric rope shovels in
