Investigation into parameters of charge explosion in the development face

The experimental data are presented for operating the charges of different groups under conditions of driving the mine workings with the use of parallel cuts. The relations connecting the optimum line of least resistance and the specific explosion energy consumptions of blast-hole charge with the ch...

Description
Summary:The experimental data are presented for operating the charges of different groups under conditions of driving the mine workings with the use of parallel cuts. The relations connecting the optimum line of least resistance and the specific explosion energy consumptions of blast-hole charge with the characteristic size of free surface are established.
