There are two main methods of extracting sand and gravel: In stationary extraction, an anchored cutter suction dredger excavates huge pits in the sea floor with depths of normally about 10 m and diameters of between 10 and 50 m. In the second method, a trailing suction hopper dredger removes sediment from the surface of the sea floor.11.19.1 Sand And Gravel Processingsand and gravel Mining Raw Material Transport Raw Material Storage Ground Material Storage Product Storage () 1 2 3 1 1 Emission point PM emissions Combustion product emissions Organic emissions 1 2 3 1 1 1 11.19.1-4 EMISSION FACTORS 11/95 Figure 11.19.1-2.

It may vary from boulder to sand sized. The size of the rock needed may depend on construction project requirements and many sizes of aggregate may be required. Once purchased, aggregate is transported to the site by trucks, railcars, or barges.

    Review of floodplain mining and risks

    Extracting sand and gravel from terraces is generally preferable to extracting sand and gravel from floodplains (Langer, 2003). In-stream mining modifies channel characteristics, especially where material is removed at a greater rate than it can replenish.
