Coal Stripping Ratio Formula

The following formula is used to calculate the stripping ratio for a given volume of overburden and volume of coal.

SR = V_o / V_c

Variables:

  • SR is the stripping ratio
  • Vo is the volume of overburden
  • Vc is the volume of coal

To calculate the stripping ratio, divide the volume of overburden by the volume of coal. This ratio helps in determining the economic feasibility of mining operations.

What is a Stripping Ratio?

The stripping ratio is a mining term used to describe the amount of overburden (material above the coal seam) that must be removed to extract a given volume of coal. It is a critical factor in determining the economic viability of a mining operation. A lower stripping ratio indicates that less overburden needs to be removed, making the mining operation more cost-effective. Conversely, a higher stripping ratio means more overburden must be removed, increasing the cost of coal extraction.

How to Calculate Stripping Ratio?

The following steps outline how to calculate the stripping ratio.

  1. First, determine the volume of overburden (Vo).
  2. Next, determine the volume of coal (Vc).
  3. Finally, calculate the stripping ratio using the formula SR = Vo / Vc.
  4. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Volume of overburden (Vo) = 500 m³

Volume of coal (Vc) = 250 m³
