Kopka I.O. Development of structural elements of the extended power to
control the mechanical effect of the explosion. - Manuscript.
Thesis for a master's degree in the specialty 8.050301 - Mining and extraction
of minerals. - National Technical University of Ukraine "Kyiv Polytechnic Institute",
Kyiv 2016.
The purpose of the master's work is to improve the efficiency of blasting in
rocks, such as reducing pereburu or even rejection of it, through the development of
scientifically based parameters and structural elements elongated hole charges.
To achieve this goal in reasonable locations intermediate detonators in hole
charges for amplification steps explosion at the base of the ledge by the interaction of
detonation waves and set minimum permissible distance from the foot well to
intermediate detonators.
Experimentally developed a new design of borehole charge, the use of which
will reduce the size pereburu or even abandon it. Made analytical studies that
confirm the effectiveness of engineering solutions.
Keywords: burovybuhovi work hole charges, the design of borehole charge
perebur, shock waves, detonation wave, detonation velocity, intermediate detonator,
embryonic crack depth zone formation cracks.
