Parametric study and dimensional analysis on prescribed hydraulic fractures in cave mining

Cave mining has become a popular underground mass mining method and extends its applications to more component orebodies at depths. To ensure continuous cave propagation, effective pre-conditioning of the orebody to improve its caveability and fragmentation sizes is essential. Hydraulic fracturing has been used as a pre-conditioning method in cave mining by creating artificial fractures in the orebody. In a previous study, the requirement for...
