Free Webinar: Run of Material Hazards Awareness in Mining

Free Webinar: Run of Material Hazards Awareness in Mining

Date: Thursday, 16 July 2026
Time: 11:00 AM–12:00 PM Eastern Time
Format: Online Webinar
Registration: Free

Join this free Run of Material Awareness Webinar to learn about one of the most serious high-consequence hazards in mining and bulk material handling operations.

A run of material, also known as a run of muck, occurs when ore, waste rock, slimes, tailings, soil, or other bulk materials move suddenly and uncontrollably under the force of gravity.

These incidents may involve loose material, stored energy, unstable ground conditions, blocked drawpoints, chutes, stockpiles, or the presence of water. They can happen without warning and expose workers to severe crushing, burial, engulfment, entrapment, and pinning hazards.

Although run of material incidents are generally low-frequency events, their consequences can be catastrophic and may result in serious injuries or fatalities.

What You Will Learn

• What a run of material or run of muck incident is
• Common causes and contributing factors
• How water can increase material instability and movement
• High-risk mining activities and locations
• Recent incident trends and reportable occurrences
• Warning signs of unstable bulk materials
• Serious injury and fatality risks
• Lessons learned from previous incidents
• Review of fatalities and official inquests
• Practical measures for preventing uncontrolled material movement

Key Discussion Topics

Understanding Run of Material Hazards

Learn how ore, tailings, waste rock, slimes, and other bulk materials can become unstable and move unexpectedly during mining, excavation, processing, stockpiling, or material-handling activities.

Incident Trends and Reportable Occurrences

The webinar will examine recent run of material incidents, common failure patterns, and the circumstances that frequently contribute to these dangerous events.

Fatalities and Inquest Findings

Participants will review selected fatal incidents and inquest findings to understand the root causes, control failures, and lessons that can help prevent similar events.

Who Should Attend?

This webinar is suitable for:

• Mining Managers and Supervisors
• HSE Managers and Safety Officers
• Mining Engineers
• Geotechnical Engineers
• Underground and Open-Pit Mining Personnel
• Processing Plant Employees
• Risk Management Professionals
• Emergency Response Teams
• Contractors and Equipment Operators
• Workers involved in stockpile, chute, drawpoint, and tailings operations

Why Attend?

This session will help mining professionals improve hazard awareness, strengthen risk assessments, identify potential run of material conditions, and implement effective controls to protect workers from crushing, burial, engulfment, and entrapment hazards.

Help create a safer mining workplace.
