Ushbu tezisda Qolmoqir karyeri bortlarida reper kuzatuvlari asosida deformatsiya jarayonini erta baholash va xavfli uchastkalarni ajratish masalasi ko‘rib chiqildi. Tadqiqotda 2025-yil fevral–iyul oylarida olingan reper o‘lchovlari tahlil qilinib, vertikal siljish tezligi, umumiy siljish amplitudasi va vaqt bo‘yicha trend belgilariga asoslangan amaliy baholash yondashuvi taklif etildi. Kuzatuv natijalari ayrim reperlarda qisqa muddat ichida keskin siljishlar yuzaga kelganini ko‘rsatdi: Rp015 nuqtasida umumiy siljish 232 mm gacha, Rp019 nuqtasida vertikal siljish tezligi 14,1 mm/kun gacha, Rp003 nuqtasida esa 197 mm gacha umumiy deformatsiya qayd etildi. Bunday holat Qolmoqir karyeri sharoitida bort turg‘unligini oddiy vizual kuzatuv bilan emas, balki reper ma’lumotlarini tezlik, yo‘nalish va takrorlanish belgisi bo‘yicha raqamli baholash orqali nazorat qilish zarurligini ko‘rsatadi. Tezisda reper kuzatuvlarini QVDXI xavf indeksi va TARP qaror tizimi bilan bog‘lash orqali xavfli zonalarni erta aniqlash hamda kon ishlarini geomekanik holatga mos ravishda boshqarish taklif qilindi.
