Introduction As a tactical mine planner an important part of the role is to continuously improve/reduce the variance between what has been forecast and what has been achieved, actual. While there are many potential parameters which can impact this variation, this post will focus on one, specifically, processing through-puts by rock type.
1. Process Mass Factor
The process mass factor (pmf) represents the mill/crusher variable input rate. This attribute is based on feed rates by material type.
The pmf is calculated by dividing the designed mill rate (by rock hardness/type) by the other rock type throughputs. For example:
- Designed (Boilerplate) process rate for the mill is 650t/hr
- Throughput for oxide is 650t/hr
- Throughput for Transition is 715t/hr
- Throughput for Primary is 575t/hr
