This video focuses on training requirements and best practices for dredging operations that extract and process sand and gravel. Dredging is an aggregate mining activity, an operation usually carried out at least partly underwater, with the purpose of extracting material from the bottom and then sending it to the shore by pipelines or pontoon-mounted conveyor belts.
River dredging is a form of river restoration and river maintenance. Over time, sand, silt and debris (branches, logs, waste) flow downstream. This is a natural phenomenon, which happens due to weathering, erosion and rivers carrying sediments. If not maintained, the materials accumulate and create a blockage.
The share among the different aggregates is: 47 % crushed rock, 41 % sand and gravel, 8 % recycled aggregates from construction and demolition waste, 2 % from marine dredging

11/95 Sand And Gravel Processing 11.19.1-1 11.19.1 Sand And Gravel Processing 11.19.1.1 Process Description1-6 by dredging involves mounting the equipment on boats or barges and removing the sand and gravel from the bottom of the body of water by suction or bucket-type dredges. After mining, the materials
The are basically two approaches to dredging, mechanical and hydraulic.Mechanical dredging involves removing sediment with machinery usually with a bucket of some type. The most common types are an excavator or clamshell bucket. Hydraulic dredging includes the use of a pump, usually barge mounted, to move material in a slurry via a pipeline. Both can be very practical and efficient depending
Dredging can be done to recover materials of commercial value; these may be high value minerals or sediments such as sand and gravel that are used by the construction industry. [2] Dredging is a four-part process: loosening the material, bringing the material to the surface (together extraction), transportation and disposal.
Published in Pile Buck magazine, Vol. 29, No. 4, 2013 Dredging impacts our lives. Dredging is an excavation activity usually carried out underwater and out of sight. It nearly always involves gathering sediments from the bottom of a pond, lake, river or harbor and then disposing of these materials at a different site. While not particularly glamorous, dredging affects our

The deep dredging DOP Dredger is fit for loosening soils at -30 m and pumping it ashore. The modular design ensures practical transport and simple assembly on site. The cutter loosens the soil and the immersed DOP dredging pump ensures a high mixture concentration an efficient dredging
Dredging is an efficient, but a relatively costly technique to reduce an internal loading problem when the right equipment is used (cutterhead suction dredging is often efficient: Figure 2).It may also serve to deepen a lake that is gradually filling in. Due to the potential content of toxic substances in the sediment a key problem of dredging is how to dispose of the sediment.
