Coal mining is only a temporary use of land, so it is vital that mine rehabilitation takes place once operations have stopped. Detailed rehabilitation or reclamation plans are designed and approved, covering the period from the start of operations until well after mining has finished. Underground mining . Underground mining currently accounts for a bigger share of world coal production .
Discover five ways the mining industry can reduce environmental impact and make its practices more sustainable. 1. LowerImpact Mining Techniques. Traditional mining techniques can have a severe impact on the environment, and some popular methods — like open pit and underground mining — present some of the most significant environmental risks.
of water (a process called 'hydraulic mining') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer mining often occurs within a streambed, it is an environmentallydestructive type of mining, releasing large quantities of sediment that can impact surface water for several miles downstream of the .

The goal of the ICCE is to promote academic and technical exchange on coastal related studies covering a wide range of topics including coastal waves, nearshore currents, coastal structures, sediment transport, coastal morphology, beach nourishment, natural hazards and coastal management.
coastal processes are well defined in NSW, and are described in the former Coastline Management Manual (CMM, NSW Government 1990) and the more recent CZMP Guidelines. Eight coastal hazards were defined in the CMM (1990). In the CZMP Guidelines, the list of hazards remains essentially the same, with focus on the hazards of: beach erosion, shoreline .

Coastal Geologic Processes. The interplay of winds, waves, tides, and currents continually reshapes coastal environments. With time, beaches and dunes shift loion through erosion and accretion of sand grains. Winds. The interaction of winds from variable directions contributes to the formation of sand dunes. In Maine, the strongest winds ...

Processes called erosion, mass movement and weathering break down and remove material from the coast. Many factors affect the rates of coastal erosion and the landforms created.
Physical processes and biological data were collected and analyzed for eight sand resource areas on the New Jersey Outer Continental Shelf to address environmental concerns raised by the potential for mining sand for beach replenishment. Nearshore wave and sediment transport patterns were modeled for existing and postdredging conditions, with borrow site sand .
· Mining, particularly gem mining, has been responsible for serious problems of soil erosion and river siltation. Extensive sand mining in some rivers has lead to the collapse of river banks, destabilising structures such as bridges and causing influx of salt water.

The process is similar to the development of acidity in clays in reclaimed tidal marshes. In mine spoil, however, drainage is generally good, and the acid constituents will be removed by leaching in a period of years. In some states of the, the legislation governing strip mining requires grading of the spoil areas to form waterretaining benches to hasten the leaching .
