Automation of drill and blast design
The available techniques for drill and blast design in underground mining were analyzed. The advantages and disadvantages of the widely used blast-hole patterns, types of cuts, and explosives are estimated. The algorithm and the program for automatic drill and blast design by optimization of spacing among blast-holes have been developed and tested. The calculations carried out for different cross-section forms have shown the advantages of the algorithm comparing to the available procedures for design.
