  • Stripping ratio Wikipedia

    In mining, stripping ratio or strip ratio refers to the amount of waste (or overburden) that must be removed to release a given ore quantity.It is a number or ratio that express how much waste is mined per unit of ore. The units of a stripping ratio can vary between mine types. For example, in coal mining the stripping ratio is commonly referred to as volume/weight..

  • What Is a Stripping Ratio? (with picture)

    04.12.2020· The stripping ratio is commonly used in the ore and coal mining processes. The stripping ratio is important due to the fact that it helps a mining company assess a mining site in order to determine the profitability before committing any resources to the mining process. A way of describing the concept of stripping ratio is by looking at it in terms of the level at which the mining

  • Coal Ratio an overview ScienceDirect Topics

    Underground coal mining today is done by both (a) room and pillar and (b) longwall mining. Generally, shallow coal seams are mined by the room and pillar technique, but deeper seams are mined by longwall methods. The latter method is gaining ground as coal seams are getting deeper. In the United States, slightly more than 50% of coal is mined by longwall faces. The trend in longwall mining is

  • How to calculate stripping ratio? ResearchGate

    For instance: If the thickness waste rock (overburden) is 100m and the thickness of coal is 50m then stripping ratio would be 2:1. That means one m3 (cubic meter) of coal would need mining two m3
