Mining system classification

Mining classes.

In this post, we will see how many mining classes we have. From Hartman, 1980, mining systems are divided into majors, surface mining and underground mining. It is easy to indentify both of it. Surface mining means everything are conducted in the surface. Changes of surface could be seen directly, such as pit! Next one is underground mining. It is vice versa with surface mining. Sometimes people don't know whether there is activity or not. This mining system is choosen to get valuable ore which has high price.

Lets see the classification of the mining system.
