In general, the higher the bench height or cut to be blasted, the larger the blasthole diameter. Large blasthole diameters can accommodate more explosives, allowing for a hole pattern to be designed with wide spacing between the blastholes. This generally means lower drilling costs with fewer holes to be drilled for a given production.
