Hazard Alert - Longwall Conveyors
Longwall conveyors have been involved in one (1) death and four (4) permanently disabling injuries in the mining industry since 1990. The Mine Safety and Health Administration would like to urge everyone to join us in promoting awareness regarding hazards encountered when working near longwall face conveyors. The fact that mining is performed in a narrow, confined passageway often requires personnel to work in close proximity to the cutting bits of the shear. Mobile equipment that can be moved independently across the longwall face introduces additional hazards. The high velocity of air directed across the longwall face and by-products of mining create hazards by restricting visibility. Exposure to roof and face sloughing can present other inherent dangers to miners. All mine personnel should be on guard to these conditions when working in longwall face areas. To avoid injuries, MSHA recommends you adhere to the following best practices.
- Maintain and wear personal protective equipment, i.e., safety glasses and hearing protection on longwall faces
- Position yourself to avoid pinch points
- Never turn your back to an operating face conveyor, when working in close proximity to moving machine parts
- Never position yourself in front of an advancing shield
- Maintain communications with personnel stationed across the longwall face
