A new framework for evaluation of rock

2019-4-1  In direct methods, measuring the amount of fragmentation is carried out by sieve analysis. Although the accuracy of this method is very high, the high cost and time-consumption are the main drawbacks of this method (Sudhakar et al., 2006). On the other hand, indirect methods including visual, empirical and image analysis techniques provide a trade-off between the accuracy of the test and the

Characterisation of block cave mining secondary

Block cave mining is a widely employed mining method around the world due to its low operating cost. One of the key factors that affects block caving mine’s productivity is fragmentation; accordingly, significant efforts have been made and are currently being made to study fragmentation processes, including the use of numerical modelling and remote sensing techniques. It is desirable to
