Влияние условий бурения и взаимодействия твердосплавных вставок коронок ударно-вращательного действия с породой на скорость бурения

Abstract

The paper deals with peculiaritres of the interaction between cemented carbide inserts of button bits and rock in a blast hole depending on specific shock energy and drilling conditions. It is shown that under specific conditions it is possible to provide the highest drilling speed and thus the lowest tool consumption, and the methods to attain this.
