ABSTRACT

The purpose of this work is to assess the factor and capabilities of the new drill bit in expanding the area of its application in various technological processes of mining both in traditional blasting and blasting.

Methods of theoretical research based on the analysis of scientific, technical and patent information, which makes it possible to summarize the experience of many researchers and scientific organizations in the form of systematic information.

The result of this work is represented by the classification of areas of application of the new drill bit of the domestic manufacturer in the technological processes of mining with the introduction of both blasting and blasting.

The scientific novelty of the work lies in the substantiation of the classification of extended zones of application of a new drill bit of domestic production with the introduction of both drilling and blasting.

Practical significance. Based on the use of a new drill bit with technical characteristics close to imported crowns, the following results can be achieved in the technological processes of mining with the use of blasting and blasting works:

- expansion of the area of application in technological processes; - increase of technical indicators;

- increase of economic indicators; - solving economic problems; - improving the safety of mining operations.

Keywords: new drill bit, blasting, non blasting.
