Skvajina zaboyka qismida polimerli konusli konstruksiyani qo’llash orqali portlash gazlarining erta chiqib ketishini kamaytirish va tog’ jinslarini parchalashga yo’naltirilgan foydali ish koeffitsientini oshirish, portlash energiyasini skvajina ichida uzoqroq ushlab turish orqali tog’ jinslarining maydalanish maydalanish sifatini yaxshilash va shu orqali xarajatlarni kamaytirish asoslab berilgan. 612026 10.5281/zenodo.20484611https://openjurnal.uz/article/portlovchi-modda-zaryadining-tiqindi-qismida-polimerli-konusni-ishlatish-yordamida-skvajina-kostruksiyasini-takomillashtirish-NIINE-2026-004https://rukoxlelgdqbshwjqpxd.supabase.co/storage/v1/object/public/article-pdfs/formatted/1780295606898-PORTLOVCHI_MODDA_ZARYADINING_TIQINDI_QISMIDA_POLIMERLI_KONUS-IJHS.pdf Kucherov, V.
