Subsurface Mining - DoDEA

Subsurface Mining. When mineral ores are too deep to get at with the surface mining techniques, subsurface mining methods are used instead. An advantage of subsurface mining is that it disturbs much less land than surface mining. ... Shaft mining is the deepest form of underground mining. It involves excavating a tunnel from the top to the ...

Subsurface geology is the study of the physical properties and location of rock and soil found below the ground surface. One of the most valuable reasons for learning about the subsurface is understanding the materials below man-made structures. These studies are commonly called geotechnical reports and are critical for building structures safely in areas with geologic
