Mar 13, 2011 In this method a floating processing station extracts loose deposits such as clay, silt, sand, gravel and any associated minerals using a bucket line, drag line andor submerged water jets. The mined material is transported hydraulically or mechanically to a washing station which may be part of the dredging rig or physically separate with subsequent processing steps to segregate

1- Contour Mining Contour Mining is most commonly used in areas that have steep or rolling terrain. It involves digging the earth above the coal line, or coal seam, along the contours of the hilly terrain. This method can be dangerous because it may cause landslides and erosion problems. 2- Strip Mining Strip Mining usually occurs on flat terrain. The earth is dug up in long cuts or strips until the coal seamOnline Chat
Shaft Sinking Soft Ground Method a WoodSteel Piling The first set of piles, forming a circle around the shaft site is started at the surface. As the piles are driven down, the ground is excavated, and a circular crib is put in every few feet. In this way the shaft is sunk in a series of short wooden cylinders.Online Chat

Dredging systems are classified as mechanical or hydraulic, depending on the method of material transport. The bucket-ladder, or bucket-line, dredge has been the traditional placer-mining tool, and it is still the most flexible method for dredging under varying conditions. It consists of a single hull supporting an excavating and lifting mechanism, beneficiation circuits, and waste-disposal systems.Online Chat
