Surface and underground mining dewatering operations may alter natural groundwater and surface water flow systems. Such operations require specialized water-handling procedures to minimize impacts in areas underlain by solution-prone carbonate rocks (e.g., limestone quarries) and underground mine pools/voids and adjacent to sensitive surface water features. Simulations of open pit mines dewatering, their flooding, and environmental impact assessment are performed using groundwater flow models. They must take into consideration both regional groundwater conditions and the specificity of mine dewatering operations. This method has been used to a great extent in Polish opencast mines since the s. However, the use of numerical models in mining Cited by: 1.
Underground Mine Dewatering Techniques • In underground mines, the conventional approach is to allow groundwater to enter the workings, effectively using the mine itself as a drain • The water entering the mine is passed along roadways (by pumping or gravity) to a deeper part of the mine (sump) or shaft bottom, to be pumped out via shaft or. Mine dewatering is the action of removing groundwater from a mine. When a mine extends below the water table groundwater will, due to gravity, infiltrate the mine workings. On some projects groundwater is a minor impediment that can be dealt with on an ad-hoc basis. In other mines, and in other geological settings, dewatering is fundamental to the viability of the mine and may require the use.
An Introduction to Mine Hydrogeology briefly describes the subject of hydrogeology so that this knowledge can be integrated into mine development emphasizes not only the hydrochemical but also the physical impacts of the hydrogeological environment on the mine and its surroundings. Geoff Beale is a worldwide expert in mine hydrology and mine water management with 37 years' hands-on experience in the extractive and mining industries. He travels globally and works as a senior technical expert for many of the large mining houses. Geoff is most noted for his global knowledge of open pit and underground mine dewatering projects, and has been involved with many of the world /5(3).

The book will be a valuable reference for all professionals who encounter polluted mine water on a regular or occasional by: Construction Dewatering and Groundwater Control is an indispensable tool for all engineering and construction professionals searching for the most up-to-date coverage of groundwater control for various purposes, the modern ways to identify and analyze site-specific situations, and the modern tools available to control them.
A water strategist and specialist in Mine ground water control,dewatering design and Slope stability studies. your growth partner in Mine dewatering Africa Some key course contents will include: •Methods of acquiring hydrogeological data and analysis •Methods of design of mine dewatering system and design criteria for mines and quarry sitesFile Size: KB.
m Hydrology drawdown around the mine site. • Most of the water pumped at the mine has been returned to the same hydrologic basin. • Extensive monitoring program, assisted by modern satellite technology and by robust modeling, has identified aquifer responses.
• Improvement of the water. Mine dewatering can be achieved using a range of groundwater control techniques, depending on the geology and the type of mine: In-pit pumping – used to pump from sump areas within the pit Perimeter dewatering wells – used to intercept lateral groundwater flow into the pit and to lower groundwater levels in advance of miningFile Size: KB.
The Second Edition explains the physical laws governing groundwater and soils, and provides practical solutions to construction dewatering problems. New chapters on groundwater computer modeling, dealing with industrial wastes and contaminated water, and operating long-term dewatering systems. the mine dewatering requirements and associated environmental impacts are discussed.
Use of Numerical Groundwater Modelling for Mine Dewatering Assessment. The water level for each dewatering well was specified to be 30 m below the elevation of the pit bottom at the end of each year, according to the yearly mine plans.

Can use porous media models to simulate most Maine bedrock hydrogeologic terrains except at small scales water flow into mines decreases with depth, with time, and with radius of openings The near-surface groundwater impact of a mine decreases with depth Tunnels located parallel to groundwater flow.
From Catchment Hydrology to Dewatering at a Copper Mine FEFLOWbyDHI. Take control of your water with our mine dewatering equipment - Duration: Excelsior Mining Hydrology. General mine dewatering (control of inflows and lowering of groundwater levels).
This is the classic dewatering activity which involves intercepting or collecting groundwater and surface water inflows and pumping the water away to create workably dry conditions in the relevant areas or levels of the mine.
The book consists of five main chapters: Chapter One—Mining and the Water Environment, Chapter Two—Mine Water Chemistry, Chapter Three—Mine Water Hydrology, Chapter Four—Active Treatment of Polluted Mine Waters, and Chapter Five—Passive Treatment of Polluted Mine Waters, as well as an Index of terms and an Appendix with a.
Water from dewatering operations of operating mines was used for the filling and management of pit lakes successfully in Germany. The mine water contributed considerably to the filling of pit. 2) Mine dewatering. When a mine is in operation, it is necessary to carry out the mine dewatering.
If the walls are stables, dewatering can be done in the bottom of the mine with the adapted pumps. In other hand, if the walls are unstable or that water inflows decrease productivity, it is better to conduct the dewatering plan in outskirts with water-wells, or directed drilling, acting as drains.
Nowhere is the conflict between economic progress and environmental quality more apparent than in the mineral extraction industries. The latter half of the 20th century saw major advances in the reclamation technologies. However, mine water pollution problems have not been addressed.
In many cases, polluted mine water long outlives the life of the mining operation.2/5(1). Many concerns rose from the potential impact of the mine dewatering on water resources availibility.
The groundwater was used for drinking, and the surface water (irrigation ponds and creeks) was extensively used for irrigation. Ina detailed hydrogeological study was conducted to File Size: KB. 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).File Size: 2MB.

The Lisheen Mine have been discharging to surface water courses since There have been no incidents of any negative impact to water volumes in any surface water course as consequence of the mine dewatering.
There have been no incidents of any impact of surface waters on ground waters caused by leakage of surface waters to ground waters. Geosyntec is known for its innovative work in storm water and surface water quality management, hydromodification management, erosion and sediment control through the design and application of Best Management Practices (BMP); groundwater resource management and cleanup; and process water treatment, reuse, and recycling.To understand the mine dewatering systems, it is necessary to know the natural conditions and structure of deposits being mined.
In underground mines, the strata that determine the hydrologic situation in the mine are the seams and the footwall and hanging wall beds. This is because only the.Too little water, and supplies must be carefully and sustainably managed.
But, too much water—in the wrong place, at the wrong time—can be a hazard. For mining and mineral processing activities, water management must be addressed at each project stage from feasibility to closure and must adhere to stringent environmental and social responsibility policies.
