Rock fragmentation control in opencast blasting

2016-4-1  1. Introduction. Rock fragmentation distribution influences a range of mining and milling processes including load and haul rates, crushing and grinding performance and ore recovery in beneficiation processes (Michaud et al., 1997).In opencast mining, where blasting is employed for excavation, the overall cost effectiveness of the production operations is compatible with optimization

Powder Mass of Coal After Impact Crushing: A New

2020-6-17  In this study, the fractal fragmentation theory is used to describe the PSD of rock after crushing. The new surface theory is adopted to characterize the rock firmness; the firmness is directly proportional to the surface energy consumption (Bond 1955; Carpinteri et al. 2004).Combining these two theories, a new index, f s, is proposed.Through a large number of experiments, the effects of the
