Iron Mining in the 1890s used drilling and blasting to loosen extremely hard iron ore (drilling was also used to locate the ore) in the open pit mining process. A compressed air drill with a diamond-tipped bit was used to bore holes three inches in diameter and about four feet deep; the holes were then filled with dynamite or nitroglycerin and the explosives detonated.
