However surface mining can be more environmentally-damaging than subsurface mining. Types of Surface Mining Open-Pit Mining. Known also as open-cast mining open-pit mining is the most common type of surface mining. Open-pit mines are enormous holes in the ground created and increased by blasting and drilling rocks apart.
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
