Powder factor can be defined as the quantity of explosives (kg) required to break a unit volume or tonne (t) of rock. The prospect of excavating rocks by blasting is characterized by a specific consumption of explosives. In the past decades, research

A new empirical formulation is presented which can be used to estimate the penetration-per-revolution for TBM tunneling, derived from TBM monitoring data of alpine tunnels in the North-West of Italy. This formulation is easy to use and allows the con

The main aim of this Thesis is to examine how the rock mass and intact rock properties influence the excavatability of rock in surface mine. One of the most important decisions in the design of surface mine is the selection of mine equipment and plan
