The most relevant concerns with mine dewatering are related to acid mine drainage and the dispersal of contaminated water into other water fonts and the general environment becoming a serious source of pollution. Types of dewatering techniques and systems. Dewatering open pit mines and underground mines is different.
Coal Mine Dewatering. Roger Howell and Vladimir Ugorets recently joined SRK (US) bringing with them significant experience in the fields of coal hydrogeology and coal mine dewatering. At the Skyline longwall coal mine in Utah, the two teamed up to determine the source of large, persistent groundwater inflows emanating from fracture ...
Xylem''s broad range of dewatering pumps enables you to work within the constraints of your mine, maximizing energy efficiency, and system decreasing downtime.

Accurate mine dewatering, depressurisation and ground water control, can save mines millions of dollars in reduced waste stripping, faster loading and improved safety. Typically, the three most expensive costs to an underground mine are labour, compressed air and water control (water control includes storm water control and mine dewatering).
Technology Data Sheet Mine Dewatering Groundwater is a common problem when mining, and developing a mine below groundwater level presents many challenges. Poorly controlled groundwater will have negative impacts on the safety, efficiency and economics of mining operations.

APS'' effluentreturn sump and pump system reduces magnetite loss in coalpreparation plants. Customdesigned bucket elevator. Customdesigned bucket elevators prevent coarse coal spillage in underground coal mine by lifting coal straight to the product belt. At .
/ : Underground Coal Mining | . The underground coal mine is called Montecristo. Tsurumi submersible highhead dewatering pumps, and LH311W, are being used in the mine and help to increase the efficiency of mining operation by their ruggedness and abrasion resistance.
Underground mining is a distinct segment of the mining sector, with coal and other minerals being extracted from depth for processing. Being underground demands high safety considerations from strata control, and the maintenance of underground road networks is undertaken in confined spaces.
Dewatering is an important part of any open pit or underground mining operation. While it can be a complex and costly process, it is instrumental. If not planned for and managed properly, mine flooding or slope failures can cause major setbacks and threaten the safety of workers.
5. Amplify the potential of tube settling which appears to be a feasible clarification technique for certain mine waters. 6. Study the dissolution of coal mine sludge in underground mines. 7. Evaluate pressure filtration and centrifuging which seem to have been prematurely disregarded as feasible methods for dewatering coal mine sludges. 8.

Dewatering a totally or partially flooded mine, or even as a normal procedure in normal mine activity, may carry a number of problems, most of which are environmentally related. This can happen in open pit mines as well as in underground mines.
4 200 4 HF trial hole (Dewatering pipe installation) ... Hydraulic fracturing in underground coal mines 5 Table 2: Results of coal core gas analysis from UIS boreholes in HF trial zone . FRACTURE DESIGN . A hydraulic fracture is normally initiated when the pressure of injected fluid overcomes the rock strength and the stress
Dewatering Active Underground Coal Mines: Technical. Underground mines contri bute a large portion of the acid drainage water which constitutes a widespread pollution problem throughout the eastern coal mining regions. In underground mines AMD is formed when iron disulfides ( marcasite, pyrite) decompose on exposure to air, forming a ...
The effects of underground coal mining on aquifer dewatering have been summarized by Sgambat, et al (1980), based on their literature survey for the eastern United States. Hobba (1981) ''has also reported on dewatered rock and reduced well yields overlying deep mines in West ia, especially in the Farmington area of western Marion County.
