Mining - Mining - Dredging: Dredging is the underwater excavation of a placer deposit by floating equipment. 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.
Typically, sand can be mined from sources above ground, such as sand dunes, but it's often dredged from deep under water in excavations known as pits. Dredges are large structures that float in manmade or natural ponds. They rely on a continuous chain of buckets or rotary cutting heads to dislodge material from below the water's surface.
Excessive instream sand mining is a threat to bridges, river banks and nearby structures. Sand mining also affects the adjoining groundwater system and the uses that local people make of the river. Instream sand mining results in the destruction of aquatic and riparian habitat through large changes in the channel morphology.

Rotary drilling was a common drilling method in the oil industry in the early 20th century. Today the method is used primarily when large diameters (over 150 mm) are required, such as in deep waterwell drilling, open-cast mining and quarrying. There are currently two types of rotary drilling, cutting, and crushing. Rotating cutting drilling
