rockfall

On April 25, 2006, the tremor triggered a rockfall inside a gold mine, and three of the 17 miners were unable to escape.

Indeed, he had helped to clear the rockfall which crushed the life out of the unfortunate miner.

They followed the yellow beam of Scotty's flashlight through the dark tunnel to the rockfall.

Then they spent the remaining time clearing more rocks from the original rockfall that had sealed them in.

He set about skirting the rockfall, still searching the ground for traces of beetle wheels.
