Two miners were installing rock bolts for ground support after scaling and bolting the back. As they were drilling a rock bolt hole a large slab of rock slid down from the hanging wall side breaking the timber supports, supporting the two miners. One miner fell 14' to a rock pile and was seriously hurt with broken ribs and collar bone, the other did not fall and was uninjured.
