ABSTRACT
Purpose. Development of a methodology for calculating the
parameters of drilling and blasting (D&B) for rise working methods of
borehole and blast-hole charges, taking into account the diameter of the
charge, the detonation characteristics of explosives (EX), the physical and
mechanical properties of rocks, their fracturing and compaction under the
action of rock pressure.
Methods. The work uses a comprehensive methodological
approach, including the development of a methodology for determining the
parameters of the (D&B), taking into account the diameter of the (EX),
the strength of the rocks in compression, the coefficients of structural weakening
and compaction under the action of rock pressure.
Findings. A new method has been developed for calculating the
rational parameters of (D&B) when conducting rising ones, in which the
distance between borehole or blast-hole in a cut is determined by the
radius of the shear zone, and for contour ones – by the radius of the zone
of intensive crushing.
Originality. The parameters of the location of borehole
or blast-hole in the raise face are implemented according to the power-law
dependence of the change in the line of least resistance (LLR) depending on
the diameter of the charge, detonation characteristics of the (EX),
physical and mechanical properties of rocks, their fracturing and
compaction under the action of rock pressure.
Practical implications. The use of a new method for
calculating the rational parameters of (D&B) for rise working make it
possible to rationalize the location of borehole or blast-hole in the raise
face, which will lead to resource saving during their sinking.
Keywords: borehole, blast-hole, explosive, drilling and
blasting, zone of intensive crushing, line of least resistance
