Safety Something YOU can live with!
Mine Type: Underground Coal

While talking with co-workers a miner was positioned between the rear of a manbus and the corner of a coal pillar. There was approximately two feet of clearance between the manbus and the rib. On the other side of a check curtain located immediately in front of the manbus a scoop operator, while sounding his warning bell, was tramming slowly and maneuvering the scoop from left-to-right so it would not tear down the curtain.

The scoop operator, who could not see the manbus, felt a "bump" when his deck cleared the curtain. The "bump" occurred when the corner of his bucket struck the front corner of the manbus. The manbus rolled back approximately two feet, fatally crushing the miner between the manbus and the coal rib. MSHA recommends the following to eliminate similar mobile equipment accidents.
