Coal Mining Stripping Ratio

Stripping ratio Wikipedia

In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore.For example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock. Stripping ratios are typically reduced to show the volume of waste removal required to extract one unit

09-05-2020· Stripping ratio is a term that is derived from the mining industry and is used in reference to the open-pit mining process. The stripping ratio method of calculating the profitability of the mining procedure is commonly used in the ore or coal mining process. In relation to its application in the mining of ore, the utility of the stripping ratio is the determination of the approximate ratio of

Stripping ratio and pit limit Basic Mining Techniques

The units for stripping ratios can vary and usually depends on the geological properties of the deposit and the commodity mined. It can be expressed in tonnes (t), or cubic meters (m 3).Usually for coal, cubic meters (m 3) or tonnes (t) are used.However, for hard rock mines where the geology is usually complex with the presence of various rock types, tonnage (t) is usually preferred.

Coal Ratio an overview ScienceDirect Topics

When coking coal to gasification coal ratio is 7, there is sufficient hydrogen supplied by the COG tri-reforming. The WGS unit can be cancelled in the new COG-CTM process, as shown in Figure 4.As the WGS unit is no longer needed in the COG-CTM process, the main operating parameters of the AGR unit and TRM unit will change accordingly.

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
