HIGH ROLLER DRILLING AND EXPLOSIVE RUPTURE OF ROCKS<\/strong><\/p>\n

Zharikov, Sergey N. \u2013 Cand.Tech.Sci., senior scientific employee, FGBUN Institute of Mining of the Ural division of the Russian Academy of Sciences, 333vista@mail.ru direct@igduran.ru 333vista@mail.ru<\/a> direct@igduran.ru<\/a><\/strong><\/em><\/p>\n<\/strong><\/em>

<\/strong><\/em>\u0423\u0414\u041a 622.026.3\/.5

Key words<\/strong>: physical and mechanical properties of rocks, roller drilling, drilling and blasting operations, explosion, drilling and blasting parameters.<\/p>\n

The paper provides findings of the investigation into the relationship between energy characteristics of roller drilling processes and explosive fracture of rocks. It is shown that consideration of parameters of production well drilling allows to model changes in strength properties of rocks in mining blocks and adjust borehole charge parameters. The presented findings of the investigation into the relationship between roller drilling processes and explosive fracture of rocks confirm that clarification of rock properties in the course of drilling and blasting operations is of high practical relevance.<\/p>\n
