Power Quality Improvement in Underground Mining

The application of electricity to the mining industry is a distinctive area of both mining and electrical engineering. Power Quality is defined as “any occurrence manifested in current, voltage, or frequency deviations that results in damage, upset or failure of end-use equipmentâ s. It is common experience that electric power of poor quality has detrimental effects on health of different ...

Guidance about underground air quality and ventilation

The basis of effective ventilation of underground mines is the adequacy of the primary ventilation system. This is the total mine air volume flow generally through the major underground workings, normally involving splits into parallel circuits. Factors that determine the total primary volume capacity (and pressure) requirements include: extent ...

Installation Quality Guidelines - DSI Underground

Fillet on Forged Head Rebar - Forged head rebar bolts should be inspected to ensure a fillet of 1/8" radius is present where the shaft connects to the forged head. Sharp transitions may weaken the bolt. Shelf Life of Resin - Resin has a practical shelf life. Although the chemical ingredients do not change with time, most resin cartridges are water based and thus dry out with age.

Determination of the Ultimate Underground Mining

2021-3-6  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 area.

What is Underground Mining? (with pictures)

Mary McMahon Entrance to a coal mine. Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ...
