Abstract
Fracturing efficiency of fluids in specific mining processes depends on reliability of data on structure and state of rocks, on pre-setting the location of fracturing origin, on choice of a fluid and its injection regime, as well as on the accepted engineering solutions. Fracturing by fluids are the processes that alter properties, structure, composition and state of rocks. Investigation of such processes offers a deeper insight into the multi-phase media (earth crust) and promotes advancement in nonconventional mining technologies.
