All MSHA-reportable accidents at Compass Minerals Louisiana Inc. operations in 2019. Fatalities appear first.
The skip is equipped with a roll-up door to allow forklifts to load supplies inside the skip. The rollers jumped the track when the door was lowered after supplies were loaded onto the skip. The condition was not detected when the skip was released into the mine. The leading edge of the door caught on shaft structure and was ripped off. The door was damaged beyond repair.
The 8' hoist ""tripped"" during its ascent in the shaft traveling empty. The hoist operator took the hoist out-of-servie per protocol. As the mine was left with one operating hoist, all miners were withdrawn to the surface. The root cause was determined to be a failed circuit control board. The hoist was returned to service after the board was replaced.
Miners were being withdrawn from the mine after a hoisting shaft was taken out of service. A door on the bottom car of the skip vibrated open during its descent and the door jammed in the shaft. The hoist operator returned the skip to the surface. The other shaft was returned to service and the remaining underground miners traveled to the surface safely.
The north skip of the friction hoist over traveled beyond its set point at the surface hitting the overhead protection in the headframe. The skip was taken out of service until the extent of damage could be ascertained, root causes identified, and corrective actions implemented.
