  Blastability and Ore Grade Assessment from Drill Monitoring for Open ...

  Mining consists of several unit operations linked to each other, and the performance of the initial stages (drilling, charging and blasting) pre-conditions the downstream unit operations in the production cycle (Ghosh 2017).For an efficient blasting, it is essential to have a well-defined characterization of the rock mass; automatization in mining allows obtaining large …
