In fact, it is the only network for mining autonomy that runs without fail. The

Determination of the Ultimate Underground

· Continuous mining of metal deposits leads the overlying strata to move, deform, and collapse, which is particularly obvious when open-pit mining and underground mining are adjacent. Once the mining depth of the adjacent open-pit lags severely behind the underground, the ultimate underground mining depth needs to be studied before the surface deformation extends to the open-pit mining

Guidance about underground air quality and ventilation

Ventilation in an underground mine is of critical importance to the occupational health and safety of underground employees. The atmosphere underground is limited and confined, and is thus readily reduced to a sub-standard (or even dangerous) condition if contaminants ( gases, dusts, fumes) produced in the course of operations are not controlled, safely extracted or diluted to acceptable
