Аннотация: Rational drilling modes for blast holes in open pit mining depend on the physical and mechanical properties of the rocks. Serially manufactured drilling tools often work in areas that do not meet the conditions of their application (especially in coal mines). The paper presents the design of a cutting bit of a cutting-rotational tyПоказать полностьюpe with hard-alloy multi-row cutting structure, as well as the dependence of the power regimes of drilling with this bit on the of drill rocks strength. © Published under licence by IOP Publishing Ltd.
