Jul 12, 2019Classically, strip mining is used to mine tar sand and coal. This technique is also referred to as open cast, open cut, or stripping. In this technique, the first step is the removal of trees, shrubs, and structures on the area to be mined, a process which is usually accomplished with heavy duty bulldozers.
