N2 - The problem of energy input optimization during the fracture process of rocks is considered to be a part of fracture mechanics. For fracture prediction the incubation time criterion is used. The Hertz solution for the contact problem is applied for calculation of the contact forces. The estimation of energy necessary for strength pulse initiation during a single cycle of vibrational drilling is performed. The dependence of this energy on the loading pulse duration is investigated. The average breaking force is evaluated.
