This is because by definition the process of strip mining involves striping away trees, plants and topsoil so that the coal can be accessed underneath. This means that surface mining destroys mountain tops, landscapes, forests and wildlife habitats. On top of that, it leads to soil erosion and destruction of agricultural land.

Miners dig tunnels deep into the earth near the place where the coal is located. The tunnels may be vertical, horizontal, or sloping. Once deep enough, the tunnels interconnect with a network of passageways going in many directions. Entries allow fresh air into the mine and give miners and equipment access to reach the ore and carry it out.

2. Coal stores safely. Unlike other fuel sources, coal stores very safely and in large quantities. It lasts indefinitely after being mined, so there isn't the need to consume the fuel immediately.

Bituminous coal is the third stage of coal production. The lignite continues receiving heavy vertical pressure until it turns a dark brown and becomes soft coal. Bituminous coal is used as an energy source in many parts of the world. The final stage of coal production is the anthracite stage. During this stage, soft coal becomes hard coal.

There are two ways in which mining can be done- underground and open-pit. Determining the type of mining depends on the depth of the deposit. Vertical shafts are dug to access the deposits through underground mining, whereas in surface or open-pit mining, soil and rocks that lie on top of the mineral deposits are removed.

Surface Mining. Surface mining includes numerous techniques and is the most common method for non-fuel minerals, producing 97% of the amount mined. Miners choose surface extraction for minerals located close to the surface. There are three main ways to mine on the surface. These methods include quarrying, open-pit mining, and strip mining.

Surface mining is accomplished by removing overburden from the coal seam and then blasting and removing the coal. The ratio of overburden excavated to the amount of coal removed is called the overburden ratio. The lower the ratio, the more productive the mine.
