Maqolada bugungi kunda kon sa'noatidagi aktual muammo bo ׳lgan qazish usullarining karyer bortlariqiyaliklari burchaklariga bo ׳lgan ta'siri ko ׳rib chiqilgan, hamda ochiq pog`onaning qiyalik shakli qiyalikburchagi o ׳rtacha qiymatiga bog ׳liqligi ko ׳rib chiqilgan.

Tayanch iboralar: optimal parametrlar, karyer borti, konni qazib olish, qiyaliklarni deformatsiyasi,karyer chizig ׳ining shakli, qiyalik burchagi, zaboy uskunalari, jinslarni joylanishi, jinslarni mustahkamligi,qazish usuli.

The article deals with such pressing problem in the mining industry for the moment as an influence of the development systems on the angles of pit slopes, as well as the dependence of the overburden slopes forms subject to the average value of the resulting angle of slope.

Key words: optimal parameters, pit side, mine development, slope deformation, pit contour shape, angle ofslope, stall equipment, rocks bedding, rock hardness, development system.
