An application of fuzzy sets to the Diggability Index

Mining shovels or excavators are basic equipment designed to dig and load material in surface mines. They are often considered the major material-handling equipment for high-production, low-cost

Diggability, a measure of dragline effectiveness and

At a surface coal mine in South Africa, large boulders necessitating secondary breakage and in some cases completely unfragmented sections of a blast resulting in low dragline diggability were encountered in the interburden blast. Twelve blasts were therefore

2010-4-12  Development of surface miner was initiated in 1970s and was continued into the early 1980s and marks a new paradigm in surface mining system (Ghose, 2008)[1]. The design concept for the surface miner is based on the milling principle and owes its origin to the road milling machines which cuts the old road surface for road construction. Since 1990s,

Models for Mining Equipment Selection

2013-1-15  The problem of equipment selection in a surface mine is complex. Many features, restrictions and criteria need to be considered (Naoum and Haidar 2000). The model must reflect the important constraints of the mining operations to a level that is acceptable and used by mining engineers. Martin consultants (Martin et al. 1982) list the
