Ushbu maqolada ochiq kon ishlarida portlatish samaradorligini oshirish, portlovchi modda zaryadining energiyasidan foydalanishni takomillashtirish masalalari ko’rib chiqiladi. 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.
