of mining machines, as well as the physical and mechan-ical properties of hard rock in the massif of the quarry. When offering the classi ﬁ cation of mining equipment by the type of action for the non-blasting preparation of hard rock for excavation, the dependence of the produc-tivity of mining machines on the rock strength was in-vestigated.
Comminution, an energy-intensive process, usually begins with blasting of rock in the mining operation followed by crushing in large, heavy machines, often used in stages and in combination with screens to minimize production of particles too fine for subsequent treatment (Sidebar 3-3). Grinding is usually done in tumbling mills, wet or dry ...

Jun 01, 2016 Effects of various rock characteristics on PPV have been studied in the past by a few researchers. Effects of rock discontinuities on blast wave propagation were presented by Ak and Konuk, 2008, Kuzu, 2008, Unified Facilities Criteria (UFC) 3-340-02, 2008, etc. Effects of different rock formations on prediction model were analyzed by Nateghi (2011).
