The mining of metal mineral resources provides an important material foundation for various fields such as electric communication construction building cemented materials and intelligent manufacturing and is an important industry that supports and ensures human survival and future development [1] [2] However the development of metal mineral
Artificial cooling of underground mines dates back to the late 19th century when naturally Figure 5 Schematic layout of a typical deep mine cooling and water reticulation system As shown in Figure 5 water is used in a semi closed loop on a typical deep mine Schutte 2007 BAC fans chilled water pumps cooling water pumps and various
UNDERGROUND PUMP STATION by Hogg and P Taylor Techpro Mining & Metallurgy Dover Place Ashford Kent TN23 lEX England Introduction This paper discusses the main problems encountered in the design of a high volume high head underground pump station
Mining Optimization Laboratory MOL University of Alberta Edmonton Canada ABSTRACT Stope layout optimization means determining the b est dimension and the locations of the stopes and number of stopes Stope layout in underground mining directly affects other significant aspects of mining such as economic value and mining recovery
The strategic design of an underground mine layout must address the location of haulage shafts decline access ventilation infrastructure level development within the stopes and stope access
Surface pump and pipe layout The surface pump and pipe layout consists of a centrifugal pump pump 2 which pumps water into a 23 000 litre tank The water from the tank is pumped by a five stage 65 kW multi stage pump pump 1 to the underground sections Figure 2 shows the surface pump and pipe layout Standard 200 mm pipes are used on surface
At the beginning of mining the ancient people unconsciously took advantage of natural ventilation According to the great work De Re Metallica written by the German mineralogist Georgius Agricola the Laurium silver mine in ancient Greece began in 600 BC when the ancients had already known that ventilation was necessary for the mining process China
Back The ceiling or roof of an underground opening Backfill Waste material used to fill the void created by mining an orebody Background Minor amounts of radioactivity due not to abnormal amounts of radioactive minerals nearby but to cosmic rays and minor residual radioactivity in the vicinity Back sample A rock sample collected from the roof or
List of Figures relating to planning from the new Underground Mine Planning textbook by Jim Dowling Jim Dowling Mining Engineer UNDERGROUND MINE PLANNING Figure Typical underground layout with a vertical shaft Figure Schematic plan view of a main pump station Note there are two settlers each can feed either of two clean
Moreover PD pumps also provide reliable efficient long distance transport which means they re well suited to operations with long pipelines or deep underground mines For higher solids applications requiring a high head Warman® DWU horizontal dewatering pumps offer robust wear life and have a number of sealing options to reduce the

Tanks will cope with inflows of up to 20L/s and pump approximately 320M Head Smaller pump stations are often daisy chained up the decline to a major Underground Mine Pump Station which will then pump directly to another major underground pump station or directly to the surface where the water slurry settles in large reservoirs for reuse
Underground Mining Stope Layout Optimization and Production Scheduling A Review of Existing Solvers and Algorithms Emmanuel Appianing 2018 Planning of an underground mine poses considerable difficulties in the areas of safety environment ground control and production scheduling To maximize the profitability of these operations an
Coal mining Underground mining In underground coal mining the working environment is completely enclosed by the geologic medium which consists of the coal seam and the overlying and underlying strata Access to the coal seam is gained by suitable openings from the surface and a network of roadways driven in the seam then facilitates the installation of
Improving underground mine conditions results in fewer ventilation related fatalities and increases productivity The objective of a subsurface ventilation system is to ensure sufficient quantity and quality of airflow in the working areas of a mine Deep level mines are typically overventilated with poor volumetric efficiencies due to old
Groundwater inflow to an underground mine will seriously affect its mining plan and engineering geology safety Groundwater models are powerful tools commonly used in the mines to develop dewatering strategies Many mines in the Kolwezi area have been present since the 1950s and groundwater flow patterns have been significantly influenced by mining

All types of underground mine access serve as permanent openings to transfer men and extracted material throughout the life of an operation Development and operating costs are predominantly
Employment Mining Underground Reg 1999 FLP equipment must be used in Restricted Zones 5 Gassy Mine Defined as a mine coal or metaliferous or tunnel in which tests on 3 successive days indicate the presence of flammable gas in an area district or main airway on the return or exhaust side 6 Gas accumulation
The most popu1 ar method of mine water control in underground mining is dewatering by pumps The optimum design of mine pumping systems should be aimed to achieve effective mine dewatering together with high operational efficiency low maintenance and overall costs The pumping systems should be designed to deal with seasonal inflow fluc
The short definition of dewatering in mining terms is simply removing groundwater for an underground mine or mining pit—anywhere that is below ground level and susceptible to collecting water The tough part of the equation is how to do it when the liquid is heavy with migrating solids high pH levels gases and other contaminants that are contrary to
