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 (e.g. marcasite, pyrite) decompose on exposure to air, forming a complex series of compounds that are highly soluble in water.
AbstractUnderground mine working changes hydraulic gradient which affect the underground surface water flow pattern. It induces slow inflow of water from, porous soil and rock mass towards the mining excavation. Mine dewatering is the removal of percolated or logged water from mines to
purpose of a dewatering system for underground and open pit coal mine is to control ground. water levels and to reduce pore water pressure in the ground so d ewatering systems are also. important...
rainy season. Mine dewatering is done through the use of sump pumps located in the lowest point of the pit, but preferably off the contact zone with country rock or regional lineaments that could be water bearing. Plates 1, 2, 3 and 4 are of sump pumping from Grootgeluk coal mine in the North West of South Africa. Plate 1 Plate 2

a network of bores and associated surface infrastructure over the underground mine footprint for mine gas predrainage (IMG) and management of goaf methane drainage to enable the - safe extraction of coal a ventilation system for the underground workings
Truflo Pumping Systems design and build bespoke industrial-strength dewatering pumps and pumping systems that enable industry heavy lifters like underground coal mines and open cut iron ore mines to remove problem water that impacts mining or construction work. Mine dewatering pumps. We pride ourselves on being the industry leader in the provision of heavy duty dewatering pumping
Design of a dewatering system requires the determination of the number, size, spacing, and penetration of wells or wellpoints and the rate at which water must be removed from the pervious strata to achieve the required groundwater
Underground dewatering . Underground dewatering and drainage is necessary to ensure that mining operations continue unhindered. Dewatering from rock faces in mine shafts, quarries, or gravel pits often contains abrasives such as sand, clay particles, drill cuttings,
Future underground coal mines will require dewatering when they penetrate the Blackhawk-Star Point aquifer. A finite- difference, three-dimensional computer model was used to estimate the inflow of water to various lengths and widths of a hypothetical dewatered mine and to estimate drawdowns of
Underground Mine Design, Planning, and Engineering ... (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 intersections. ...
Dewatering of mines by the use of vertical wells drilled from the surface is a common practice, especially in open pit mines. The advantage of this system of dewatering is drainage ahead of mining, discharge of clean water, and practically no interference with the mining operation.

The roadways underground are divided into 2 groups, those carrying fresh air into the workings (intake airways) and those carrying used air back out (return airways). Adjoining intake and return airways are separated by the coal pillars or by installing stoppings (most commonly in the form of a wall of some kind) in any interconnecting ...
