Essay

The dependence of change of relocation bias of blast-hole charge explosive cartridges in time was found as the experimental results. On the base of analytical investigations there was found the dependence of maximum possible explosion crater radius value on the parameter "The complete energy of charges explosion production in a blast hole" in different conditions. There was also suggested construction of cartridge and blast-hole explosive charging for realization of the inverse method of initialization of explosive charges. Taking into account all the investigations there was developed drilling-and-blasting operations technology during vertical shaft sinking.
