Short ways reduce open pit mine operation cost:
1. Proper design: remember proper preparation prevent poor performance (5p's key of good operation system). When it comes to open pit mining I always like to make mine plan and Design first as the key ways to optimize and garantee profitability.
See through this: The following factors are the dictator of stripping ratio (Stripping cost), Drilling and Blasting, loading and haulage operation, then processing operation.
Find the factors below and how that affects the about operation:
Factor number 1: Bench height: This is the maximum vertical extension of the mine bench also define as the vertical distance from the toe to crest of a bench. This factor determine the type of loading equipment that will be strictly permit in the mine for loading because, the loading boom of the equipment must not be longer than the bench height. Small loading equipment means low production or high cost of getting enough loading equipment that will fit for your production target as shown by your fleet design.
It also affect dilution control in the mine, heigh bench height result into large hole Drilling, and large powder factor which may result in external dilution through overbreak, internal dilution through backbreak. It also affect selective loading. All which increase production cost by increasing haulage cost (more waste move to Processing plant), increase mine life (by reducing recovery mill efficiency) and also reduce ore grade automatically reducing ore market value.
