Many modern coal mines are large scale high productivity operations with layout equipment and production scheduling tailored to suit the geological characteristics of the particular coal deposit The delineation of these characteristics is as much a part of an exploration program as assessment of the amount of coal actually available for use1/4/ 32 In opencast mining where blasting is employed for excavation the overall cost effectiveness of the production operations is compatible with optimization of drilling and blasting parameters Rock fragmentation depends upon two groups of variables rock mass properties which cannot be controlled and drill and blast design parameters that can be controlled and optimized
