Bitcoin Mining Hardware Guide The best Bitcoin mining hardware has evolved dramatically since 2009. At first, miners used their central processing unit (CPU) to mine, but soon this wasn''t fast enough and it bogged down the system resources of the host computer. Miners quickly moved on to using the graphical processing unit (GPU) in computer graphics cards because they were able to hash data 50

When a resource occurs in shallow horizontal deposits near the surface, the most effective mining method may be strip mining. During strip mining, layers of surface soil and rock are removed from large areas to expose the resource. After heavy machinery removes the soil and rock, the resource is extracted. Then, the soil and rock are replaced.
The two main types of mining are surface mining and underground mining. Mining is further divided into several other egories including room and pillar mining, slope mining, block caving, quarrying, openpit mining and in situ mining.
