ai.sys

Many call this is the age of information. It is perhaps more accurate to call it the age of data since not everyone has the ability to truly gain from all the data they collect. Many are either lost in the data, or misled by it. Yet, the promise of being informed by data remains. Further still, in many cases the data can be leveraged through systems engineering techniques to develop strategies and optimize processes.

Mission

The ai.sys group conducts research on gaining insight from data, models systems and develops computational tools for education and research.

UteAnalytics, Our Free Analytics Tool

We wish to empower domain experts who are not programmers, with machine learning. Check out our free tool.

 

Mine to Mill 

Due to confidentiality agreements, the insights on mine to mill project cannot be shared at the moment.

 

Language of safety

Can narratives of safety incidents from one organization help analyze narratives of safety incidents from another organization? It seems they can. Our team was able to successfully analyze reports from a mining partner using natural language processing (NLP) based analytics tools developed for public domain sources. The tools can be used to define data driven leading indicators at industrial sites. Download our peer reviewed papers on the topic.

Sensor data quality

Researchers from the group were able to identify errors in temperature sensors of gold stripping vessels at a gold mine in Alaska when the errors were still small. In industrial settings, sensor calibrations are often a year or more apart. Industrial processes operate on faulty data until errors become so large as to be obvious. The US oil industry alone loses $20 billion annually from operating on faulty sensor data.

Material Flow

How long does it take for material dumped at crushers to reach the mills? Management at a large mine in Mongolia had this question. This question is quite common when management focuses on mine-to-mill grade control. The answer is tricky, as most mines have several silos/stockpiles between crushers. Researchers from the group used a variety of numerical tools on material flow and grade data, to answer the question.

Rajive Ganguli, PhD, PE

Dr. Ganguli, who formed this group, has been teaching and applying artificial intelligence (ai) since before it was cool in the mining industry. He has applied ai and systems engineering (sys) in a wide variety of contexts, and not just in the mineral industry. He has worked in mines in India and in the US. Click here for more information.

Bryony Richards, PhD

Dr. Richards is a diverse geoscientist with a recognized background in the integration of cross-disciplinary scientific methods; petrological methods, high-resolution imaging, remote sensing (including magnetic and gravity interpretation), the understanding of complex datasets, igneous and metamorphic geochemistry, and radiochemistry (thermochronology, geochronology, and stable isotopes). Her research interests are focused on resource exploration and using cross-disciplinary scientific methods to deepen our understanding of Earth processes. 

Rambabu Pothina, PhD

Dr. Pothina has expertise in the areas of industrial sensor error detection, data-mining, and big data. His research interests include mine planning and design, mine safety, industrial systems optimization, and innovation. He has worked in engineering and supervisory capacities for several major mining companies in metal, aggregates, and cement sectors in US, Canada, and India.

Narmandakh Sarantsatsral, PhD

Narmandakh has been a part of the ai.sys group from its inception. He recently graduated from the doctoral program in mining engineering. Prior to this, he was with Erdenet Mining Corporation, Mongolia, as a chief engineer.

Lewis Oduro

Lewis recently graduated from the master's program in mining engineering, and his currently in the mining industry. He continues to engage with the group particularly with regards to his graduate work, UteAnalytics. He came to us from Ghana. He was with Newmont prior to his graduate studies.

Raviteja Tatikonda

Teja is in the master's program in mining engineering. He comes to us from India. He worked for Hindustan Zinc Limited and Hutti Gold Mines in India.

Elijah Marshall

Elijah is in the master's program in mining engineering. He comes to us from Ghana. He worked for Newmont for several years before joining our team.

Ishmael Anafo

Ishmael is in the master's program in mining engineering. He comes to us from Ghana. He worked for Kinross and others before joining our team.

New Students

We are expecting new graduate students to join us shortly. Like all members of this team, they have significant mining industry experience.

What are we up to?

MINE TO MILL

We are assisting one of the largest mining companies in the world understand how geology impacts metal throughput at one of their operations.

IMPACT OF COVID

COVID has had a dramatic impact on society, some of which has opened up very interesting opportunities to study complicated issues. For example, how are traffic, air quality, public policy and hospital visits related? The ai.sys group is currently working with faculty in atmospheric sciences, medical school and political science to understand exactly that.

ANALYZING SAFETY NARRATIVES

Whether they are work place observations made through an app, or reports entered into a mine safety health management systems, textual narratives are an important source of information that can be leveraged to identify patterns and design safety interventions.  In partnership with mines, we are using natural language processing (NLP) to design algorithms (more suited for mining industry related narratives) to gain key insights.

Dynamic Mill Simulator

We are developing a training simulator for mill operators. This is to help mill operators get a holistic view of the grinding circuit. The simulator allows for customizable mill circuits. Features include SAG mill ball mill, screens, cyclones and circuit splitter.
