If you need it, we have a wide range of MSHA-approved dewatering solutions available. For open pit dewatering: Manage rainwater, improve seepage water management, and lower the water table to prevent ground water influx. For underground dewatering: Keep water out of sumps, optimize main drainage, and boost water out of shafts.
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
Mine dewatering techniques. Dewatering and groundwater control is an important part of many open pit and underground mines. Effective dewatering is a pre-requisite for safe and efficient mining. Poorly controlled groundwater will waste money, slow down mining and potentially cause adverse environmental impacts. However, techniques are available to successful control groundwater.

"Open Pit Dewatering Pumping & Piping" is a two day pump training course which has been specifically designed for site-based dewatering teams, design engineers and hydrogeologists who are tasked with operating, maintaining, trouble-shooting or designing open pit (mine) dewatering systems.
Dewatering is a significant engineer-ing design and critical path com-ponent, and represents an on-going operational cost for open pit mining operations. Dewatering an open pit mine is an important process and its implications should be thoroughly un-derstood before selecting the pumping equipment and designing the pumping system.
Drainage Control and Mine Dewatering at Faro Open Pit Mine ABSTRACT by Randy S. Lopaschuk, Geological/Geotechnical Engineer, Cyprus Anvil Mining Corporation, Faro, Yukon Territory, Canada There have been many problems associated with drainage control and mine dewatering since mining started at the Faro open pit mine.
The dewatering aspects of transition from open pit to underground mine is also covered. You will be educated in the basic theory of mine dewatering and the application of the knowledge to real world situations. The steps required to design and implement a successful and cost effective dewatering
Aug 03, 2015· preene PERIMETER DEWATERING WELLS Perimeter dewatering wells are used to intercept lateral groundwater flow into the pit and lower groundwater levels in advance of mining 15. preene SUB-HORIZONTAL SLOPE DRAINS Where perimeter dewatering wells are used to dewater the pit, the pore water pressures in the slope may drain more slowly.
Pumps & Systems, March 2013 Mining applications are as diverse as construction or water and wastewater applications. Each jobsite has specific requirements and needs. Underground and open pit mines have several layout and design obstacles. Regardless of the mine and its setup, water is a mine’s biggest enemy. Getting water out—and keeping it out—is the primary focus of any mine plan.
Xylem’s broad range of dewatering pumps enables you to work within the constraints of your mine, maximizing energy efficiency, and system decreasing down-time. Xylem offers a wide range of pump technologies, from submersible to dry mount, ensuring the right pump for every job. Rental options are also available in certain areas.
Mar 20, 2017· While drawing water from open pit and underground mines is crucial, and the task that most people think about when the subject of dewatering comes up, we also tackle other issues relating to fluid movement and transfer, including moisture in tailings storage facilities, which has potential to destabilise the facility.
Oct 29, 2018· Turnkey dewatering specialist Carl Hamm PPS, together with Solrock Mining Services (MC & P) will introduce an innovation that will revolutionise dewatering in open pit mines. CEO Chris Munnick has over his career established a reputation for focusing on and successfully delivering new dewatering innovations into the market.

Groundwater control by pumping (also known as dewatering) is the method of temporarily lowering groundwater levels to allow excavation for construction and mining projects. As discussed in a previous blog,groundwater control can be achieved by pumping methods or, alternatively, by exclusion methods.
Problems and Solutions. Pennsylvania coal has been mined since the 1800’s.Before 1977 under-regulated mining left open pits, coal refuse, spoil piles, acid mine drainage, open shafts, erosion, clogged streams, undermined areas with subsidence potential, underground fires and damaged buildings throughout the nation. States began promulgating reclamation laws as early as the 1930’s.
