文摘A very popular point of view on the production 'rate of mining mineral resources has been held for long time;that is. if the marker price is static, the function of discount rate makes an optimum production rate decrease with the time. The point is proved incorrect by the author through a detail study on the relationship between the operation costs and the production rate by using several different mathematics mathods. Also a new mathematic model of searching for optimum production rate and mine life in the underground is inculded, which is more practical in application.
