Maqolada tog‘li hududlardagi ruda konlarini ochiq–yer osti usulida qazib olish sharoitida kontur zahiralarini o‘zlashtirish samaradorligini oshirish masalalari ko‘rib chiqilgan. Tadqiqotning dolzarbligi karer konturidan tashqarida joylashgan zahiralarni murakkablashib borayotgan kon-geologik va kon-texnik sha-roitlarda qazib olish zarurati bilan izohlanadi. Karer maydonidan kontur va konturdan tashqaridagi zahiralarni o‘zlashtirishda asosiy ochuvchi element sifatida foyda-lanish imkoniyatlari tahlil qilingan. Karer maydonidan ochuvchi lahimlar joylashtirish va rudani tashish uchun foydalanish kapital kon ishlari hajmini kamaytirishi, za-hiralarni ekspluatatsiyaga kiritish muddatlarini qisqartirishi hamda kombinatsiyalashgan qazib olishning iqtisodiy samaradorligini oshirishi ko‘rsatib berilgan.
Ishda zahiralarning karer elementlariga nisbatan joylashuvi, ularning yotish chuqurigi va qabul qilingan transport sxemasiga bog‘liq holda ochishning mumkin bo‘lgan texnologik sxemalari qiyosiy tahlil qilingan. Stvol, qiya va gorizontal lahimlar hamda karer maydonidan foydalanilgan holda kontur va konturdan tashqaridagi zahiralarni ochish variantlari ishlab chiqilib, tizimlashtirilgan. Har bir variant uchun kon-geologik sharoitlar, karer parametrlari va ishlarni xavfsiz olib borish talablari hisobga olingan holda ularning ratsional qo‘llash sohalari aniqlangan. Olingan natijalar tog‘li hududlardagi ruda konlarini ochiq–yer osti usulida qazib olishda ochish tizimlarini loyihalash va optimallashtirishda qo‘llanishi mumkin.
