Types of Surface Mining | American Mine Services
In particular, surface mining is used to retrieve sand, gravel, stones, coal, iron and other metals. There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open-pit mining, mountaintop removal, dredging and highwall mining.

8.4.2c Longwall Mining | ABC 123: Testing Site / Course
8.4.2c Longwall Mining. Longwall mining applies to thin, bedded deposits, with uniform thickness and large horizontal extension. Typical deposits are coal seams, potash layers or conglomerates, trona, and gold reefs. Longwalls are found in nearly horizontal deposits of coal and trona, whereas in metal/nonmetal deposits, a steeper dip is tolerated.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
Diamond Mining Methods | Diamond Museum Cape Town
There are two types of pipe mining, namely open-pit mining and underground mining. Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into ...
