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 nonblasting 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.

Mining Terminology Disarray

The 20th Century is deservedly considered as the most technologically advanced in the human history. This is not only because of aerospace, communications, computer sciences, etc., but mining as well. A short list of technologies which have emerged within that time includes solution mining, coal gasification, in-situ leaching, borehole mining, O&G stimulation and several more. Many great scientists and engineers contributed their talent and experience in the commercial success of these technologies. There's an abundance of mining-related scientific and engineering publications, presentations, internet blogs, and alike. Meanwhile, due to the large number of different scientific and engineering schools and their worldwide geography, there is a certain muddle and confusion in this modern mining processes terminology. There are situations when the same process has more than one name and vise-versa, two or more different processes have the same title. This work is an attempt to clarify and bring in order some mining terminology based on existing and prevalent terms, meanings and definitions.
