Optimisation of ash stockpile height to minimise haul truck diesel costs
Optimisation of ash stockpile height to minimise haul truck diesel costs
(OP)
Hi,
How would I find out the optimum height of an ash stockpile in order to minimize diesel haulage costs, for a CAT haul truck?
My stockpile height is to be between 25m to 50m.
I have worked out the fuel consumption and time taken from the start point to the haulage area, based on required speeds obtained from the Rimpull-speed-gradeability curves for that particular CAT truck. But I'm not sure how to relate this to the optimum stockpile height.
Any advice?
Thanks,

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

For a large stockpile, say a mining wastepile for planned pit, geotechnical eng. will determine bench height and maximum number of lifts. I do not see where diesel is an issue. If the facility is to be rehabilitated at end of mine, footprint is really the issue here.

I have a friend who has expertise at economic justifications for conveying versus truck hauling, especially for materials such as CCR. You might think about some conveying solutions to allow a steeper angle. Haul trucks to pile and then conveying. Depends on your budget. Operating budget versus capital expenditure.
