Use of measurement while drilling techniques for improved

Rock mass properties for a mining area are generally determined based on information obtained from the ore - body model (based on exploration data) visual observations in combination with other indices obtained from physical sample testing or geophysical logging One of these indices is the blastability index Blastability is generally dependent upon the geological and geomechanical
