According to the research, each ton of coal mine will pollute 1 cubic meter to 2.5 cubic meters of water resources. [10] Mine water is essential for mine operation. In the process of mining, mine water will be contaminated with different intensity, especially acidic chemicals which formed acid mine drainage (AMD). A large number of sulfides ...

It contains plentiful natural resources, including mineral ores, oil and gas. These rich mineral resources explain why the Central Asian Orogenic Belt is also called the Central Asian metallogenic domain, which is one of the largest metallogenic domains in the world.

Edie Creek has been a historic gold and silver mining area since its discovery in 1926. [2] Located about 5 km south-west of Wau, it was the centre of one of the first major gold rushes in PNG before World War II. [2] Large amounts of gold have been extracted by both alluvial and underground mining. [2]
Seabed mineral resources such as manganese nodules, cobalt-rich crust and submarine hydrothermal deposits are located at depths over 1,000 m (3,300 ft). [4] Most of these deep sea resources are unexplored at the seabed. Much of the seabed has a depth of 3,000 m (9,800 ft) to 6,000 m (20,000 ft).
This list of mines in Indonesia is subsidiary to the list of mines article and lists working, defunct and future mines in the country and is organised by the primary mineral output. For practical purposes stone, marble and other quarries may be included in this list.
Tin mining in Perak around 1910.. Tin mining is one of the earliest type of mining operated in Malaysia, starting in the 1820s in Perak and in 1824 in Selangor. [1] The development of mining industries in Malaysia attracted many Chinese immigrants who came to the state in 18th and 19th centuries to work and develop the mines. [2]
In the Eastern Pacific, including the area around Juan Fernández Islands and the abyssal plain offshore Loa River. [ 14 ] The largest of these deposits in terms of nodule abundance and metal concentration occur in the Clarion–Clipperton zone on vast abyssal plains in the deep ocean between 4,000 and 6,000 m (13,000 and 20,000 ft).
