Mining Drills. Drilling equipment is perhaps the most commonly used in mining activities, specifically underground mining operations. They are used to drill and loosen the mineral ore for easy transportation to the surface. Miners widely use them because they reduce the number of people working in the mines and are also costeffective to use.
