Short-Rounds Using PCF Concept

Professor, Laurentian University

The penetrating cone fracture (PCF) concept is based upon the initiation and propagation of the controlled fracture by pressurizing a shallow hole. Foremost, critical analysis of the previous studies will be carried out. The current drilling and blasting practice in deep mines will be examined by visiting the operating mines. Initial field work exploring the application of PCF concept will be conducted. Other techniques with a potential of application to deep mining conditions will also be examined.
