AI-Driven Incident Classification in Mining Safety

Introduction

Safety incident reporting and classification in the mining sector are crucial for maintaining a secure work environment and complying with regulations. Existing incident reporting software requires users to classify data using a complex, domain-expert taxonomy. Manual data classification leads to a critical problem—users tasked with classification often lack the expertise to categorise incidents accurately, resulting in misclassified data that requires time-consuming review and correction by domain experts.

In July 2020, a large diversified mining company approached our team with a compelling question: Could we automatically leverage AI to classify safety incident data on users' behalf? The goal was to allow users to provide only a textual description of an incident, with AI handling the complex task of classifying the incident in terms of agency and mechanism. This article explores our journey from 2020 to 2024, detailing our innovative solutions, their outcomes, and how the landscape of incident classification in mining safety has evolved with the advent of Large Language Models (LLMs).

The Challenge: Bridging the Expertise Gap

The client faced several interconnected challenges in incident classification and reporting:

1. Complex Taxonomy: The existing system classified incidents using a data taxonomy specific to the safety domain. While comprehensive, this taxonomy is complex for non-experts to navigate effectively.
2. User Knowledge Gap: Users reporting incidents needed more expertise to accurately classify them according to the required agency and mechanism categories. This gap between user knowledge and the complexity of the classification system was at the root of many subsequent issues.
3. Data Quality Issues: Misclassifications led to unreliable data. Domain experts had to perform time-consuming reviews and corrections after the fact, creating a substantial backlog of incidents needing verification.
4. Inefficient Process: The need for expert review created bottlenecks in the incident management process. This delay in finalising incident reports would slow the implementation of critical safety measures.
5. Inaccurate Reporting: Data misclassification could lead to erroneous reporting, resulting in incorrect conclusions drawn from misclassified data and the downstream consequences of allocating resources to the wrong root causes.
6. Impaired Decision-Making: Inaccurate reporting and analysis compromise the ability to make informed safety decisions.

The ultimate goal of our project was multifaceted:

1. Simplify the user interface, allowing users to focus on providing detailed incident descriptions without the burden of complex classification.
2. Automate the complex classification process using AI, ensuring consistency and accuracy.
3. Significantly improve the quality of the underlying data.
4. Enable more accurate reporting and analysis.
5. Enhance the quality of safety decision-making by providing a more reliable foundation of incident data.

By addressing these challenges, we aimed to create a system that not only eased the burden on users and experts but also dramatically improved the mining industry's ability to understand, predict, and prevent safety incidents. The potential impact was significant: more effective safety measures, better resource allocation, and a safer working environment for miners.

The 2020 Approach: NLP and Machine Learning

Our 2020 solution aimed to bridge the gap between user-provided descriptions and expert-level classifications using Natural Language Processing (NLP) and Machine Learning (ML). Here's how we approached it:

1. Data Collection and Preparation: We gathered a large dataset of historical incident reports, including descriptions and correct agency/mechanism classifications. This data was crucial for training our AI models.

2. Text Preprocessing: We developed a robust system to clean and standardise the incident descriptions, making them suitable for analysis by our ML models.

3. Feature Extraction: We used advanced text analysis techniques to convert the preprocessed descriptions into a format our ML models could understand and learn from.

4. Model Training: We developed separate agency and mechanism classification models and trained them on our prepared dataset.

5. Real-time Classification System: We implemented a system that could process new incident descriptions in real time and provide classifications based on our trained models.

Outcomes and Challenges

This approach yielded several positive outcomes:

1. Reduced User Burden: Users could focus on providing detailed incident descriptions without worrying about complex classifications.

2. Improved Consistency: The ML models provided more consistent classifications than non-expert users.

3. Faster Processing: Automated classification significantly reduced the time from incident reporting to data availability.

However, we also faced challenges:

1. Model Accuracy: While better than non-expert users, the model's accuracy still needed to match that of domain experts, especially for rare or complex incidents.

2. Limited Context Understanding: The ML models needed more nuanced descriptions or incidents that required broader contextual understanding.

3. Adaptation to New Categories: As new types of incidents or classification categories emerged, the model required retraining, which was time-consuming.

The 2024 Approach: Leveraging Large Language Models

As we look towards 2024, the rapid advancements in artificial intelligence, particularly in Large Language Models (LLMs), offer exciting new possibilities for revolutionising incident classification in mining safety.

Here's how we would approach this challenge using cutting-edge LLM technology:

1. Customising a Mining-Specific AI Model

We would select a state-of-the-art LLM, such as GPT-4 or its successors, and tailor it to the mining industry. This process, known as fine-tuning, involves:

• Feeding the model thousands of accurately classified incident reports from the mining sector.
• Teaching the AI to understand mining-specific terminology and safety concepts.
• Ensuring the model can differentiate between subtle variations in incident types is crucial in mining.

This customisation would result in an AI that 'speaks the language' of mining safety, capable of understanding and classifying incidents with a level of nuance previously only possible by human experts.

Developing an Intuitive Classification System

Rather than requiring users to navigate complex classification forms, we would create a simple, conversation-like interface. Users would describe incidents in their own words, just as they might to a colleague. The AI would then:

• Analyse the description in real-time.
• Ask relevant follow-up questions if needed.
• Provide a suggested classification, complete with an explanation of its reasoning.

This approach would make the incident reporting process more natural and less time-consuming for users while still capturing all necessary details.

Implementing a 'Learning Loop' with Expert Oversight

To ensure ongoing accuracy and improvement, we would establish a system where:

• Safety experts regularly review a sample of AI-classified incidents.
• These experts can quickly correct any misclassifications.
• The AI model automatically learns from these corrections, continuously enhancing its accuracy.

This process would combine AI's efficiency with human experts' irreplaceable insight, eventually creating a more innovative and reliable system.

Expanding Beyond Classification

We would train our AI to do more than classify incidents. It would also:

• Identify potential root causes by analysing patterns across multiple incidents.
• Flag unusual incidents that might require immediate attention from safety managers.

By providing these additional insights, AI would become a powerful tool for proactive safety management rather than just a classification system.

Ensuring Seamless Integration

Finally, we would design the system to integrate smoothly with existing safety management software and processes.

• Creating user-friendly dashboards for safety managers to monitor trends and insights.
• Developing APIs to allow the AI to communicate with other safety and operational systems.
• Ensuring the system can generate reports in formats required for regulatory compliance.

This integration would ensure that the AI's advanced capabilities translate into practical, day-to-day improvements in safety management.

By leveraging these cutting-edge LLM technologies, we could create a system that classifies incidents with unprecedented accuracy and is a comprehensive tool for enhancing overall safety in the mining industry. This approach would save time, reduce errors, and, most importantly, create safer working environments for miners.
