Quick Guide to Soft Rock Mining Underground Mining

Jan 28, 2021 Soft rock mining refers to the process of extracting soft underground minerals such as oil, coal, shale, and potash from soft rock mineral resources. Since mineral deposits of soft or sedimentary rocks are evenly layered and relatively soft, methods for mining such materials are much more different from those used to extract hard rock minerals.
