Strip Mining Strip mining gets its name from the fact that the process involves stripping the surface away from the mineral that's being excavated (usually coal). Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucket-wheel excavators. This type of mining makes sense when the mineral is near the surface.

The entry from the earth's surface to the underground mine may be created via a horizontal or vertical tunnel (also known as adit, shaft, and decline). Underground mining is used when the ore body is too deep to be profitably mined by open pit, or when the quality of the ore body is high enough to cover up the expenses.

Shaft mining is where you dig a hole either down into the ground to retrieve some resource, or you dig the hole horizontally into the side of a hill for the same purpose. The other main form of mining is strip mining, where all the dirt is removed from the top of the layer where the resource lies. Sponsored by JetBrains

Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. [1] Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.

The quarrying process consists of separating large blocks, sometimes called loafs, from the surrounding rock. These blocks may be 6 metres high by 6 metres deep and 12 to 18 metres (about 40 to 60 feet) long, and they may weigh in the range of 1,200 to 2,000 tons. (Such large blocks are subsequently divided into mill blocks weighing 15 to 70 tons.)

About every 400 or 500 ft. the shaft is widened; sills are laid along the side of the shaft as shown, and cross pieces are then bolted under the end plates and centers of the shaft, resting on the sills. The shaft set is then blocked and wedged on top of these cross pieces. Regular posts are then placed under the bearers when sinking is resumed.
