Challenge Description

In the Phase-X Mine Design Challenge, Unearthed has partnered with one of the world’s largest resources companies, BHP Billiton, to offer an online challenge drawn from the company’s real life operational data and mine planning scenarios.

Teams from universities and research organisations across the globe will compete to create the best algorithm for optimising open pit mining phases, drawing from gigabytes of BHP Billiton’s operational data.  No mining experience required.

Open pit mining for minerals such as iron ore and nickel requires complex and informed planning. The order in which specific areas of the pit are mined is dependent on a number of critical factors, such as the processing capacity at the mine, the grade (quality) of the mineral and the maximum slope of the pit walls. With thousands of options available, choosing which area of the pit to mine and in what order is an important and valuable challenge.

The winner of the competition could receive up to $50,000 AUD.

BHP Billiton has collaborated with Unearthed on this challenge as part of its innovation agenda, aimed at improving safe productivity and maintaining competitiveness through the development of innovative approaches to real-life business challenges.

Registration

Once you have registered you will received a link to download the block model data, additional challenge description, and access to a forum to post questions.

Submissions

Submissions will open on the 24th of March and close on the 7th of October.  Register and we’ll let you know as soon as submissions open. In the meantime once you register you’ll be able to download the full dataset and get a head start!

Note that submissions are ranked based on score and the date of submission, so you should submit as soon as possible. You can make multiple submissions if you improve your algorithm later.

Prizes

A $50,000 Grand prize is up for grabs for the top submission. And for the top 5 submissions a Travel prize is available to present at a special 2 hour sessions at the 24th National Conference of the Australian Society for Operations Research in Canberra, Australia on the 17th of November.  Full details can be found in the competition terms and conditions listed below.

Frequently Asked Questions

How will my submission be scored?

There are two parts to the competition - processing the block models to develop the most efficient mining phase design with the highest net present value (NPV). When the competition is open you will need to submit both the algorithm in executable form and an output of the results from the three open block models in csv form.

The score of a valid submission is the total sum of its percentage deviation (positive or negative) from the nominal results of the three hidden problems.

The highest score submission will be considered as the winner. Submission scores that are within 5% of each other will be considered equal. In the event of a tie, the winner will be the submission that consumes the minimum total CPU time. If still there is a tie then it will be broken by ranking the contestants with the date of their submission, giving priority to earlier submission.

Who owns the Intellectual Property in my submission?

You always retain full ownership of your IP.

While the competition is open you will need to submit an executable of your code for judging purposes on the hidden data sets.

When submissions close if you are ranked in the top 5 we will invite you to submit your code. You’ll need to grant us a 30 day non-exclusive license to the code solely for us to assess it.

If you are selected as the grand prize winner, in return for the $50,000 prize you must assign a perpetual non-exclusive royalty-free license to BHP Billiton. You will continue to own your code, and are free to do whatever you like with it, including selling it to others.

Can I submit multiple times?

Yes, you can submit early and then refine your algorithm and submit again later. Your algorithm will be ranked based on its best score.

If two or more participants have submissions with the same score, then they will be ranked based on the date they were submitted, so we encourage you to submit early.
