EFFECT OF THE INITIAL LOCATION ON SAND AND GRAVEL …
Sand and gravel mining from riverbeds is a major supply of construction materials. A mining pit in a riverbed is very unstable and subject to scouring and deposition which results in migration of the pit. In this paper, migration of a rectangular pit in a straight channel bed composed of uniform sediments is simulated with SSIIM model. The ...
Mining Techniques for Sand & Gravel | Sciencing
Sand dunes can also be mined by dredging or hydraulic methods. This involves a high pressure jet of water to wash the sand into a pond where it is pumped to a storage pile or tank. Where sand is present in the form of loose sandstone, drilling and blasting are necessary. The blasting reduces the sandstone to smaller pieces that are placed in trucks by front end loaders.

The mode of operations of these illegal small-scale sand mining requires critical scrutiny and regulation. This calls for a lot of supervision from the appropriate state agencies and Kusimu (2014) suggests creation of more offices of these agencies in localities where these activities are rife. The study showed that two types of sand mining, namely instream and flood plain mining, are ...
11.19.1 Sand And Gravel Processing
Industrial sand and gravel typically are mined from open pits of naturally occurring quartz-rich sand and sandstone. Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant. Figure 11.19 ...
