    Open Pit vs Underground Mining Methods While most mineral deposits can be mined by either surface or underground methods, some minerals can only be recovered in a hybrid manner, usually by initial extracted by open pit mining, followed by underground methods Here, a brief comparison is made with respect to the advantages and disadvantages of various mining methods Figures 1a and 1b show27/04/2015· Underground method, as the term explains it, is about mining underground and drilling deeper into earth’s surface It requires more money that will be spent on drilling, assuring miners’ safety, and erecting safetycentric equipment There’s also copious amount of preparations needed to execute successful drillings and setting up effectual ventilation methodsThe many advantages of underground miningIn surface mining, the rock barrier on top of the deposit is removed to access the ore However, sometimes, such deposits occur too far below to access them from the surface In such cases, they are extracted by leaving the overlying rock intact, and accessing the deposit directly from below This method is called underground mining, whose types are explained belowHere are the Types of Underground Mining and Their
