The research on the dynamic impact mitigation of at rockburst-prone min-eral ore deposits
The studies of the rock mass state under the block mining conditions were undertaken at the Tashtagol deposit. The bearing pressure zones were detected in the host rock mass in the vicinity of the goaf floor. It is established that the electrometric resistance of a rock mass tends to vary in time in response to the block blasting with the different-mass explosive charges. The dynamic activity was assessed before and after the coyote blasting operations.
