Maqolada turli hil konstruksiya skvajinali zaryadlarning energiyasini boshqarish orqali kon jinslarining maydalanishmuammolari keltirilgan. Bunda to'gridan to'g'ri va qarama qarshi yo'naltirilgan, hamda ko'p nuqtali skvajinalizaryadlarning konstruksiyasi ko'rib chiqilgan. Portlatilgan kon jinslarining granulometrik analizi shuni ko'rsatadiki,taklif qilingan usullarda maydalangan kon jinsi +400 mm tashkil etib traditsion usullar bo'yicha portlatishdan 1,4marta kam harajat bo'lib, kon jinsi +800 mm tashkil qiladi, kon jinslari esa traditsion usulda 4 marotoba kamayganiniко 'rsatadi.

Control problems o f crushing rocks by energy o f explosion by well charges o f explosives various designs are given inthe article. The designs o f well charges by air gaps, direct and counter, as well as multi-point initiation o f boreholecharges are considered. Analysis o f the granulometric composition o f the blasted rock mass showed that the yield o ffractions up to 400 mm with these initiation methods increased by an average o f 1.4 times in comparison with the conventionalblasting method, And at initiation with the help o f threads DSH - in 1,2 times; The output o f fractions morethan 800 mm with the proposed method o f initiation decreased more than 4-fold.
