Abstract

This article is devoted to the conceptual development of the transition from drill and blast excavation to a non-blasting method for the preparation of hard rock before excavation at construction material deposits. The scientific and technical literature on the problems in the blasting of hard rock in preparation for excavation is analysed. A classification of mining equipment for the non-blasting development of a rock mass for excavation has been developed, taking into account the nature of the operation of mining equipment. The concept of the transition from drill and blast excavation to non-blasting methods in the preparation of mined rock in non-metallic material quarries is presented. The research results of the parameter determination of the elements of the system for the development of non-blasting equipment at a limestone quarry are presented. The economic efficiency of a hydraulic excavator with a ripper tooth for developing limestone with a strength of up to 30 MPa is established.
