- MZN Extraction Mine Type
- Definition
- The surface material is removed in successive parallel strips to expose the mineral, the spoil from each new strip being placed in the previously excavated one.
- Description
- They are used in generally flat terrain and are commenced with a trench or 'box cut' made through the overburden to expose a portion of the mineral seam. This trench is extended, in a series of cuts 30 to 60 metres wide, to the limits of the property in the strike direction. After mineral removal, a second cut is made parallel to the first one, and the overburden material from this cut is placed in the void of the first cut. The process is repeated in successive parallel cuts until the stripping ratio indicates that continued surface mining is uneconomical.
