Here are two of the main categories of mining:
Underground Mining - Underground modes of access include drift, slope, and shaft mining, and actual mining methods include longwall and room and pillar mining. Drift mines enter horizontally into the side of a hill and mine the coal within the hill. Slope mines usually begin in a valley bottom, and a tunnel slopes down to the coal to be mined. Shaft mines are the deepest mines; a vertical shaft with an elevator is made from the surface down to the coal.
Surface Mining - Surface-mining methods include area, contour, mountaintop removal, and auger mining. Area mines are surface mines that remove shallow coal over a broad area where the land is fairly flat. Huge dragline shovels commonly remove rocks overlying the coal (called overburden).
Types of surface mining include open-pit mining, quarrying, strip mining, and mountaintop removal mining. These methods involve removing overlying vegetation, soil, and rock to access ore or minerals near the surface. Each type of mining has various environmental impacts that should be considered.
Surface mining methods for coal include strip mining, open-pit mining, and mountaintop removal. Subsurface mining methods involve underground mining techniques such as room and pillar mining, longwall mining, and shaft mining. Each method has its own advantages and challenges in extracting coal from the earth.
There are a lot of different divisions. In general, you might separate them into surface mining, such as a quarry, strip mine, or open pit mine, and underground mining, consisting of shafts and adits.
The three types of mining -strip mining,open pit mining,and shaft mining
Some surface mining methods include open-pit mining, strip mining, mountaintop removal mining, and placer mining. These methods involve removing the overlying material to access the desired mineral deposits near the surface. Surface mining is often used for coal, metals, and other minerals that are located close to the Earth's surface.
Gold is recovered by three basic mining methods: placer mining of alluvial deposits, lode or vein mining, and recovery as a by-product of base-metal mining.

Two common methods used to remove rocks and minerals from the ground are surface mining, where machinery is used to extract materials from the surface, and underground mining, where tunnels are dug to access deposits deep underground. Both methods have different environmental impacts and safety considerations.

mining
Strip mining is the most common method.
panning,shaft mining,cradling and puddling
Gold is typically found through mining methods such as placer mining, hard rock mining, and hydraulic mining. These methods involve extracting gold-bearing ore from the earth and then processing it to extract the gold. Modern methods also include using advanced technologies such as satellite imagery and geochemical analysis to locate potential gold deposits.
