Optimization of mucking and hoisting operation in conventional shaft sinking

Ausgabe 01_2015 The mostly applied shaft sinking method is conventional shaft sinking by drilling and blasting. Using this method, almost any shaft geometry is feasible and challenging ground conditions can be sunk through with acceptable sinking performances. Particularly mucking and hoisting operations of the sinking cycle have a relevant impact on sinking performance and offer a considerable optimization potential. Nevertheless ...
