Annotation: When carrying out drilling and blasting work in the Yoshlik-I open pit mining, work was considered to improve the structure of the holes and improve the efficiency of blasting work, and to direct the effect of poisonous gases that may occur as a result of blasting into a useful coefficient of work. Drilling of explosive hole at different angles in the array has resulted in increased exposure patterns of the hole in the explosion. It was found that it is possible to achieve good preservation of the slope of the ridge, which will be formed after blowing up the oblique squages.

Keywords: Inclined hole, explosive, seismic impact distance, hole of construction, degree of fraction, rock, blast energy.
