The management personnel of mine production, about loss and depletion management, are estimated to be spoken every day, every month, and every year. What is its essential meaning, the exact extent of economic significance, estimated that very few people can say clearly, Taking a gold mine, for example, will make it clear these issues.

The index of mining depletion and loss is an important control indicator for mining, which is used to evaluate the level of mining technology. In fact, mining depletion and loss are also economic indicators, which have a great impact on the economic benefits of the mine.

There are many articles about mining depletion and loss, most of which explain the meaning, calculation method, production management, etc., and the economic significance of depletion and loss management is rarely discussed. This paper focuses on the importance of mining depletion and loss management from the economic significance.

I. Impact of mining depletion and loss on mine economic benefits

In order to obtain good economic benefits, mining enterprises must optimize the input-output ratio and obtain the maximum output and quality of the mined products with certain production inputs. The depletion and loss of ore in the mining process has direct and indirect effects on the economic benefits of the enterprise, mainly in the following aspects.

1. The impact of mining depletion on the economic benefits of mines

The depletion of ore increases the amount of waste rock, which directly leads to an increase in the cost of mining, transportation and mineral processing, and an increase in invalid input;

The depletion of ore will reduce the quality of the product, and the price of the product will decrease for the pure mining enterprise whose final product is the original ore;

3 The depletion of ore reduces the grade of ore. Under the same treatment scale, the output of mineral products (fine powder or metal) decreases, and the economic benefits decrease.

2. Impact of mining losses on mine economic benefits

The loss of ore directly leads to a decrease in mined ore and does not produce the desired economic effect;

The loss of ore will increase the infrastructure and depreciation and amortization of the tonnage, which will increase the total cost of the tonnage;

The ore loss causes the mineral reserves to be exhausted prematurely. Early investment and mining of new ore fields, mining areas and sections will reduce the economic benefits of mining enterprises.

Second, take gold mine as an example to calculate

1. Assumption

For a certain gold mine, the main parameters are as follows:

2. The impact of mining lean economy

The depletion rate increased by 1% (the loss is unchanged), and the results are as follows: the mine with a production scale of 500,000 tons, the economic loss per ton of mine is 9.85 yuan, and the annual economic loss is 4.92 million yuan.

If the depletion rate increases by 2%, the economic impact is even greater.

3. Economic impact of mining losses

The loss rate increased by 1% (depleted and constant), and the results were as follows: the mine with a production scale of 500,000 tons, the economic loss of the mine was 3.87 yuan, and the annual economic loss was 1.93 million yuan.

Third, the conclusion

Loss and depletion are not only used as technical indicators, but also as economic indicators.

In general, the impact of the depletion of mining losses on economic benefits is still very large.

I really don't know, I am scared.
