Get MoreFailure in industrial processes is often related to wear and can cause significant problems. It is estimated that approximately 1–4% of the gross national product for an industrialized nation is related to abrasive wear. This work aims to numerically predict development of wear for full-scale mining applications in harsh sub-arctic conditions.
Get MoreMining manuals provide loading cycle times or production rates of excavators as function of the volume of the bucket and a qualitative description of the ease of excavation of the rock or its diggability (Sweigard 1998, Atkinson 1998). Kuznetsov et al. (1997) use a measure of rock strength to estimate the diggability of non-blasted rocks.
