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 open pit ...

Models For Mining Equipment Selection

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

Diggability A Measure Of Dragline Effectiveness And

Dec 01, 1996 Abstract. Given the capital intensity of the dragline operation coupled with rising cost of explosives, the onus is on mine operators to make maximum use of explosives in blasting to assist dragline diggability. 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

Derivation Of A Diggability Index For Surface Mine

The work was conducted in operating British surface coal mines and presents a technique for diggability assessment in that mining and geotechnical environment. A diggability index is proposed which consideres both ground conditions and excavating equipment capabilities. This is supported by reference to back-analysis of several mine excavating case studies.

Jun 14, 2019 equipment selection in surface mining is primarily depends on determination of ease of excavation in site. The assessing of ease of excavation of rocks has been based on empirical and intuitive processes. Traditionally the problem has been reduced to determining whether blasting or ripping is required prior to mechanical excavation.
