Briefly describe the definition and classification of stripping ratios and answer the following questions

1 What are the units of stripping ratio? Can the classification of stripping ratio be determined according to the unit of stripping ratio?

2 What is the difference and relationship between the average stripping ratio and the incremental stripping ratio?

What is the difference and relationship between the stripping ratio and the incremental stripping ratio?

4 What is the difference between the production stripping ratio and the incremental stripping ratio?

What is the difference and correlation between the ratio of reserves and stripping and the ratio of raw ore stripping?

A: The ratio of the amount of stripped rock to the amount of ore mined in a particular area of â€‹â€‹open pit mining or during a specific period of time is called the stripping ratio.

Classification: reserve stripping ratio, raw ore stripping ratio

1 unit: m^3/m^3, t/t, m^3/t

2 The average stripping ratio refers to the ratio of the amount of rock in the single boundary closure to the amount of ore, and the incremental stripping ratio refers to the ratio of the amount of rock in the composite boundary closure to the amount of ore, which describes the complex boundary. Stripping relationship. The average stripping ratio is a special form of incremental stripping ratio.

3 The boundary stripping ratio refers to the ratio of the amount of rock to the amount of ore on the marginal surface of the open-pit mining boundary, which is both a marginal value and a limit value. The incremental stripping ratio refers to the ratio of the amount of rock in the composite boundary closure to the amount of ore, which describes the stripping relationship of the composite boundary.

4 Production stripping ratio refers to the ratio of the amount of stripped rock to the amount of ore mined in a certain period after the open pit mine is put into production. The incremental stripping ratio refers to the ratio of the amount of rock in the composite boundary closure to the amount of ore, which describes the stripping relationship of the composite boundary.

5 Reserve stripping ratio refers to the ratio of the amount of waste rock to the amount of ore calculated according to the geological exploration report in the open-pit mining boundary. The ore stripping ratio refers to the ratio of the amount of stripped rock to the amount of mined ore that is obtained after considering the loss of ore and the depletion in the same range. In the design calculation, the reserve stripping ratio is generally adopted, which is directly determined according to the geological exploration data. In the production statistics, in order to facilitate the work, the ore stripping ratio is often used, and the two can be converted to each other.
