During the 2nd and 4th of December of 2019, the 28th MPES 2019 Conference (Mine Planning and Equipment Selection) was held in Perth, Western Australia. It should be noted that MPES has become one of the most prestigious international forums to discuss and promote the technological transfer internationally in mining, with a particular focus on the development and application of new methods and technologies for mining planning and equipment.

In the meeting, works were presented on mining resource modeling and sustainable development, geometalurgical planning, artificial intelligence and automation, rock mechanics, health and safety in mining operations, mining economy, among others.

The Delphos Mine Planning Laboratory counted actively with the participation of 4 of its members through presentations with the publication of articles in proceedings book in MPES 2019.

• Sergio Montané, Pierre Nancel-Penard & Nelson Morales: Optimization and Sequencing a semiautomated ramp design in underground mining: a case study.
• Enrique Jélvez, Nelson Morales & Julián Ortíz: Impact of geological uncertainty at different stages of the open-pit mine production planning process.

Below are some images of Delphos presentations in MPES 2019.
