Comments on coastal mining and processes

Mining in Cornwall and Devon - Wikipedia

The areas of Cornwall around Gwennap and St Day and on the coast around Porthtowan were among the richest mining areas in the world. At its height the Cornish tin mining industry had around 600 steam engines working to pump out the mines (many mines reached under the sea and some went down to great depths).

Mining - Wikipedia

Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction.

impact on the coastal environment of marine aggregates mining

The higher demand for construction materials and the depletion of land sources, coupled with sterner environmental restrictions, led suppliers to turn to the sea, particularly to the near-shore areas. Several of these mining operations are illegal, many are damaging for the coastal and off-shore environment, some are.

Titanium - Mineral Fact Sheets - Australian Mines Atlas

Mineral sands were first mined in Australia in the 1930s at Byron Bay, on the north coast of New South Wales. By the late 1940s, rutile and zircon mining started in Queensland and further south in New South Wales. Mining of ilmenite began in the mid-1950s near Bunbury in southwest.

Submarine Mines | Cornish Mining World Heritage Site

The engine houses of Cornwall's coastal mines are positioned so dramatically because the mine shafts needed to be sunk as close as possible to the productive mineral lodes. Locating the shafts part way down the cliff also reduced the time and money required to sink the shaft. Positioning the pumping engines nearer sea.

Mining for Fish | Middle East Research and Information Project

The reduction of the river's outflow, which once deflected offshore currents, together with a lessened silt load reaching the sea, has meant that sea currents now produce net erosion along the delta's coastline, altering coastal configuration and wetland channels to the sea. These processes have affected water circulation.
