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).
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.
Longwell Mining and Open-Pit Mining

what are the different types of surface mining
types of underground mining methods - unsuported(natural suport)mining method -saported(artificial support)mining method - caving method

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.

panning,shaft mining,cradling and puddling
Strip mining is the most common method.
their is Panning,cradling,shaft mining,dry blowing,Puddling and dredging!!
Longwell Mining and Open-Pit Mining
Due to the low value of bauxite, mining is usually strip mined
