摘要

Though the mill can usually make much better production estimates through their measurement systems (that is, less variation), this knowledge rarely benefits the mine. [...] even if the mine does a reasonably good job of estimating expected production at the grade control level (in situ), issues such as blast movement, poor mining practice and inefficient ore/waste classification make for a disconnect between the in situ estimates of the mine and the estimates from the concentrator. [...] mine-mill metal accounting and reconciliation systems need a procedure for ongoing evaluation, where historical trends are continuously examined over time and where issues highlighted over one or more accounting periods are investigated and corrected.
