How miners can improve water management. By Ralph ... at a Bowen Basin coal mine, ... future redraw and mitigates the environmental impact of mine dewatering. Water Management in Coal Mining Project: … 2009-07-12· Zubayer Zaman Water management is one of the major aspects of coal mining, specially for open pit mines.
Abstract. Mining activities impact the nearby environment, causing the so-called mining hazards. The land subsidence phenomena caused by the dewatering of the mines are listed among the mining-induced catastrophic geohazards slowly affecting extensive areas around the opencasts.
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.
Dewatering from rock faces in mine shafts, quarries, or gravel pits often contains abrasives such as sand, clay particles, drill cuttings, and other potentially damaging objects, and the pH value is usually very low. Grundfos dewatering pumps are designed to work in the toughest environments.
The objective of the study was to undertake a review of tailings dewatering technologies currently used in Australia and Overseas and technologies with the potential to improve tailings dewatering either from a quality (moisture and handleability) or commercial (costs per tonne of tailings) perspective.
Such current practices as aeration, recirculation and neutralization are discussed. Additional techniques at various stages of development, such as thickening, conditioning, and dewatering are evaluated for use in coal mine drainage treatment. The most promising coal mine sludge dewatering technique appears to be vacuum filtration.

Typical sedimentary sequences overlying coal seams consist of interbedded sandstones, siltstones, shales, and rider coal seams. In many surface coal mine settings, these sediments are saturated; and prior dewatering of them is necessary for effective and economic mining, including the stacking of saturated spoils.
DEWATERING FOR SURFACE COAL MINES O'Rourke, J. E. and O'Connor, K. Woodward-Clyde Coo s.ultants Three Embarcadero Center San Francisco, California 94111 ABSTRACT This paper examines the potential benefits to surface coal mining by predrainage of mine properties. Conditions are examined in the Interior Coa 1 Province of the United
Coal dewatering plant ships equipment to Indonesia ... GTL Energy, a coal dewatering plant that operated only sporadically, quietly closes its operation and the equipment will soon be sent to Indonesia.
Dewatering coal tailings at KHAA KHUDAG COAL MINE, Mongolia. The Ukhaa Khudag coal mine lies in the heart of one of the harshest climate zones on earth: the southern Gobi desert. In the winter, its pipelines and coal tailings dam would freeze. In the summer, much of its water would evaporate.
This report presents the technical results of a pilot-scale dewatering operation and assesses the cost-effectiveness of the technique. The study should provide the coal mining industry with useful concepts and general guidance in deter- mining the technical and economical feasibility of thus dewatering an active coal mine.
Most coal mines in Indonesia extend below the water table. Some mines have nearby surface water, either in perennial or ephemeral streams with potential for active recharge to the groundwater system behind the mine walls. Dewatering discharges need settlement ponds prior …

Flowservices recently supplied 13 clamp- on flowmeters to a major Coal Seam Gas company in the Surat Basin working with coal mine-dewatering. A local electrical company had previously installed a number of mechanical meters. Whilst the cost was low they often failed after a short time in service.
Hence, many Indonesian companies and wealthy families decided to acquire coal mining concessions on Sumatra or Kalimantan in the late 2000s. Coal became known as the "new gold". What drove this increase in Indonesia's coal production and export? Coal is the dominating force in power generation.
