Stress state of rocks near stope in the "Karnasurt" mine
Abstract. The stress state of stope workings of the "Karnasurt" mine has been studied using numerical modelling. The "Karnasurt" mine develops thin flat-dipping ore deposits by systems with open stoping and without failures and flushing of workings. Modelling has been carried out under gravitational and gravity-tectonic stress state of the rock mass. It has been established that stability of the large-span stope workings is provided, mainly, due to action of large tectonic stresses of subhorizontal direction.
