Research of technologies and technical means for drilling and blasting of horizontal mine workings

The main scientific and practical results of the study of technologies and technical means for drilling and blasting horizontal and inclined (up to 120) mine workings based on high-performance self-propelled drilling, loading and delivery and auxiliary equipment taking into account the study of changing geomechanical, mining and hydro-geological conditions of the field are presented and new designs of prismatic cuts. A technological audit of drilling and blasting of horizontal openings and calculation of the parameters of drilling and blasting of prismatic cuts was performed, which is provided by self-propelled drilling machines, for example, Russian, Ukrainian and Belarusian manufacturers, as well as Atlas Copco, Sandvik, Tamrock and others. The research results can be used in underground mining of ore deposits of complex structure.
