The productivity of a rock charger operates on a front surface mining is influenced by many variables. We identified those considered most important and for a type charger model number measurements were taken in the field. Using linear regression expressions that allow predicting the dependent variable as a function of the independent variables were deducted. The dependent variables were identified : production tonnage , fill factor , and delay characteristics of the excavation. The independent variables were : bench height , boot size and fragmentation. Least squares system is used to predict the performance and cost given certain values of the remaining variables in the regression equation but there is the problem of selecting the dependent variable. Two or more variables in the system might seem equally dependent , since the process to test significance of the variable can be iffy .Downloads
