An airblast hazard simulation engine for block caving ...

Introduction. Airblast in block caving situations is a very dangerous situation with potential loss of life for operators and damage to mining equipment. 1 Airblasts occur when air pockets are present within the material that is currently being extracted through the drawpoints (Fig. 1). 2 As the material close to the drawpoints (defined as the muck-pile) becomes stagnant, the block falling at ...
