Assessment of category of the rock burst hazard for the Charmitan gold deposit

Abstract

The article analyzes the results of studying the physical-mechanical properties of the rocks of the Charmitan gold deposit (Uzbekistan) and estimates the liability of the deposit to rock bursts. It is shown that there are rocks and ores at the deposit with high strength properties that are capable to accumulate significant potential energy and undergo brittle failure. It is concluded that the Charmitan field, by the physical-mechanical parameters of host rocks, belongs to the category characterized by the manifestation of rock pressure in a dynamic form.

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

“…It is important to bear in mind that rock mass classification systems are based on empirical relations that should be cross-checked in the course of actual mining by geologists and geomechanics using appropriate techniques of field investigation and engineering evaluation [9][10][11][12][13][14].…”
