On November 4, 2013, a 36 year-old longwall chief, with 16 years of experience, was killed while shoveling loose coal and rock between the coal face and the pan line on a longwall section. The victim received crushing injuries when a solid piece of coal and cap rock fell from the coal face, striking and pinning him against the face side of the pan line. The coal/rock combination measured approximately 4 feet and 10-inches long, by 2 feet and 3 inches wide, and up to 24 inches thick.
Best Practices
- Conduct a thorough examination of the roof, face, and ribs, including a visual examination and a sound and vibration test prior to miners being assigned to work or travel through an area.
- Correct hazardous roof, face, or rib conditions before any work or travel is permitted in the affected area.
- Use a bar of suitable length and design for removing loose or unconsolidated material.
- Support the exposed longwall roof, face, and ribs by mechanical means in the immediate work area.
- Train all miners in hazard recognition and safe work practices that are assigned to perform work on the longwall face.
- Apply additional safety precautions in areas where geological changes and anomalies in strata are present.
- Post a certified foreman at the work area when maintenance is being performed.
- De-energize the face conveyor, notify the headgate operator, and disconnect power at the control station while work is being performed on the face conveyor (pan). Do not energize the conveyor until all persons are off the face side of the conveyor and the conveyor is supported adequately from inadvertent movement.
