Estimates of blasting production can be made by knowing the size of equipment and the type of job. For example, a 10 cm track-mounted drill and 25 cubic meter per minute air-compressor may prepare 40 cubic meters per hour for small, shallow blasts and 140 cubic meters per hour for larger, deeper blasts including quarry development to produce rock surfacing. A major cost will be explosives. For
