Different Types of Mining Techniques

Mining is the method used to extricate valuable resources from the ground. It is done to obtain any supply that cannot be fabricated or grown through artificial ways. More precisely, mining is employed to extricate non-renewable resources like fossil fuels, minerals, and even water.There are four main techniques of mining, and that is the following.

Underground Mining

Comparatively costly and often used to get to deeper deposits, underground mining includes digging down into the ground and making shafts and tunnels that reach the resources' deposits. Ore and other materials can then be brought up to the surface for dispensation, while waste rock can be detached. There are different underground mining types that are categorized based on the type of shafts used, and methods applied to get to a deposit. For occurrence, drift mining uses horizontal tunnels, while slope mining employs diagonal shafts to reach deposits. The type of underground mining method used is generally based on the zone's geology, especially the amount of ground support required to make mining safe.

Surface Mining

Surface mining involves the exclusion of plant life, soil, and potentially substratum to be able to access resource deposits. It is typically used for fairly narrow, non-precious deposits. The two primary types of surface mining are open-pit mining and strip mining. Open-pit mining involves mining out rocks to make an open pit or borrow pit, from which resources are then hauled out. Strip mining is generally used to extricate shallow, bedded deposits, where a mineral layer is roofed by a layer of soft loam and weathered rocks. 

Placer Mining

Placer mining is usually done in riverbeds, sands, or other sedimentary atmospheres and involves sifting valuable resources from sediments. In addition to gold, platinum, gemstones, tin, and other materials can be extricated through place mining. At least 50 percent of the world's titanium comes from this the Placer mining operation. For efficient and effective mining operations, mine support cylinder is used. 

In-Situ Mining

In-situ mining is also known as solution mining, it does not involve eliminating intact ore from underneath the earth's surface. As an alternative, it involves pumping chemicals underground to soften resource-containing ore and then pumping back up to the surface, where it can be treated to recuperate minerals. This method is mainly employed in uranium mining.
