Abstract

Currently, the branches of JSC Kuzbassrazrezugol are working to optimize drilling and blasting operations in order to increase the efficiency of mining operations and reduce negative manifestations of industrial mass explosions carried out at open-pit mining sites. In this regard, pilot explosions were carried out in the areas of open mining operations of the organization. This article presents the results of instrumental measurements performed during pilot industrial explosions at open-pit mining sites of branches of JSC Kuzbassrazrezugol.

The purpose of the study was to check the reliability of the criteria for assessing the danger of negative manifestations of mass explosions at the facilities selected for pilot explosions.

Keywords

Open mining operations, Industrial mass explosions, Shock air wave, Seismic impact, Well charge, Soil vibrations, Spreading of rock pieces.
