Bonanza Explorations, Inc. · Struck by falling object
Miner was placing a 10' drill steel into a pre-drilled 6' hole. The miner was holding the steel when a rock approx. 4' x 4' x 3' began to fall in the area of the drill hole. The miner retreated as the steel bearing the weight of the rock hit the back of the knee and knocked him to the ground.
