Drill Hole


(shpur), a man-made cylindrical cavity in a solid medium, such as rock or concrete, with a diameter up to 75 mm and a depth up to 5 m. Drill holes are used to place blasting charges, to anchor supports, and to force water or cement into the surrounding rock. The holes are drilled with hammer drills, electric drills, and other light-duty drilling machines.
