In «Tulskoe NIGP» new production technologies of diamond bits were developed and implemented. This technologies allow improve exploitation characteristics of developed equipment and upgrade serial equipment. Examples of technological background organization of serial and modern diamond bit were given for objects «Central-Kola» expedition and geological organizations of republic Uzbekistan.

Significant expansion of diamond drilling has put forward a new area of research related to the study of the nature of diamond drill bits in conditions of high contact temperatures, which are characterized by the destruction of the hardest rocks and drilling with compressed air blowing ...

Exploration of the Tyrnyauz deposit, carried out on the flanks mainly by means of mining and drilling operations, is complicated not only by specific features of the highlands, but mainly by thick (from 50 to 180 m) deluvial-moraine deposits. These sediments are represented by unconnected fragments of altered rocks of different hardness and abrasiveness: mudstones, siltstones, tuff-sandstones, granite-gneisses and hornblende of various compositions. In addition, on the northern slopes of the ridge there are widespread areas of permafrost, which makes the specifics of drilling operations close to the conditions of the Far North.
