Abstract
The article discusses the issues of environmental safety during massive explosions at the open-pit mines of SUEK-Kuzbass JSC. In the paper, the parameters of drilling and blasting operations in the performance of massive explosions at the Zarechny open-pit mine are analyzed; the requirements for the calculation of seismically hazardous zones from explosions in the open- pit mine for underground mine workings of the Taldinskaya-Zapadnaya 2 mine are determined; the conditions of seismic safety of underground mine workings during explosions in the sections by means of instrumental measurements of the parameters of seismic-explosive waves (velocity, acceleration of displacement) are established; in the ShotPlus 5 program, the switching circuits of explosive networks are analyzed; the dependence of the maximum mass of charges that are simultaneously blasted on the distance is established, which ensures the seismic safety of underground mine workings; recommendations for determining the safe parameters of drilling and blasting operations in the sections are given.
