A project in coarse-grain sandstone is being investigated. Field drilling tests proved that air-track drills with 4-in. B bits can achieve a penetration rate of 2.1 ft/min. Assume that it takes 5 min to change a bit. The drills use 12-ft steel. The blasting pattern will be 8 × 10 ft with 2 ft of subdrilling. The average depth to finish grade is 18 ft. The drilling production must match that of the loading and hauling operations, which is 320 bcy/hr. Assuming a 45-min production hour drilling, how many drill units will be required?
