Maqolada Qalmoqqir mis-molibden-oltin ochiq koni bort qiyaliklarining turg'unligi lokal (alohida pog'ona) va global (to'liq bort) masshtablarda, tektonik kuch ta'sirini hisobga olgan holda baholangan. Birinchi usul sifatida yassi sirpanish sirti sxemasiga asoslangan, Excel muhitida tuzilgan chegaraviy muvozanat modeli, ikkinchi usul sifatida esa SSAP2010 (6.1-versiya) dasturida yetti hisob usuli (Janbu, Spencer, Sarma I va II, Morgenstern–Prays, Chen–Morgenstern, Borselli) qo'llanildi. Balandligi 15 m bo'lgan pog'ona uchun tektonik kuch hisobga olinmaganda xavfsizlik koeffitsienti FS = 3,63–5,04 ni, hisobga olinganda esa FS ≈ 1,02 va undan past qiymatni tashkil etdi. Balandligi 442,5 m bo'lgan 25 pog'onali bort uchun FS = 1,32–1,41 olindi. Ikki mustaqil usul natijalarining mosligi xulosalar ishonchliligini tasdiqlaydi; bort deformatsiyalarini monitoring qilish hamda global modelga tektonik va seysmik ta'sirlarni kiritish tavsiya etiladi.
