The application of grey clustering decision in determining the rational open-pit limit of mining

The basic theory of grey decision-making and grey clustering decision is discussed in this paper. A kind of grey cluster assessment method for determining the rational open-pit limit of mining based on grey fixed weight clustering and white-ionization weight function is proposed. Grey clustering decision is used in determine the rational open-pit limit of mining, and it succeeds in obtaining the better and the optimal open-pit-stages limit design, which is obtained from the counting result of parameter-function method. The Application shows the method is practical for determining the rational open-pit limit of mining. A new method is provided in determining the rational open-pit limit of mining in this paper.
