C ontinuous mining systems have been established in coal and soft rock mining for about a century now and the technology to cut through hard rock has been successfully used in civil engineering projects since the late 1950s. One would think that by now, continuous hard rock mining would also be a reality but it is not. The possibility of the technology being applied to hard rock mining has in ...
In southern West ia, however, surface and underground mining produce nearly equal amounts of coal. As a result of new equipment, companies now excavate more coal with far fewer miners. Today, West ia produces as much coal as ever but employs less than 18,000 miners, down from a high of 125,000 in 1948.
Machine used in Gary, West ia digs the coal and loads it onto the car. With it, three men could do the work of 50 in the old way. G/O Media may get a commission

Mining Mining Horizontal openings: drifts: All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exploration. A drift running parallel to the ore body and lying in the footwall is called a footwall drift, and drifts ...

Motor graders are heavy equipment used for fine grading and for moving small amounts of dirt. They have a long blade that can be adjusted to meet certain angles to create a flat surface. They can also be fitted with a second blade in front of the front axle and in some instances can be used for underground mining.
2. Underground mining. Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline. Underground mining is practical when:
