Rating assessment of rocks and ores in the conditions of the Kyzyl-alma deposit of Angren mine department

Abstract

A comparative analysis of assessing the stability of rock masses was carried out based on rating indicators that are used at foreign underground mining enterprises. An assessment of the state of the rock mass at the Razvedochnaya and Kyzyl Alma mines of the Angren mine was carried out. The method for determining the category of disturbance of an ore and rock massif is effective, gives a quick assessment of the state of the massif - the international Barton rating system is recommended to be used in problem areas (unstable, stressed, weakened, fractured, disturbed (tectonic faults), watered massif, etc.) during excavation, fastening and maintaining workings, for qualitative and quantitative assessment of the state of the ore and rock mass.
