Underground mining (soft rock) Wikipedia

Underground soft rock mining is a group of underground mining techniques used to extract coal, oil shale, potash and other minerals or geological materials from sedimentary ("soft") rocks. Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in igneous or metamorphic rocks (see Underground mining

The method of extracting coal, oil shale, potash and other minerals from soft or sedimentary rocks are called underground soft rock mining. In contrast to this is the underground hard rock mining where techniques are used to extract minerals that are hard.

Recovery of Copper by Solution Mining Methods

commonly derived from massive sedimentary deposits by in-situ methods. Prior to 2000, mining operations in the Gulf of Mexico region recovered sulfur by a solution mining method, known as the Frasch process, which injected superheated water to melt the sulfur so it can be pumped to the surface (Christensen et. al., 1991). Approximately

Alluvial Mining Gold Mining Sedimentary Rock
