Quarrying mudstones and shales in a yorkstone quarry.
Watch a Doosan Daewoo 340 Excavator, digging through the shale and mudstone to reach the big sandstone blocks below. The mudstones and Shales are removed from the top of the sandstone blocks in a cleared section/area of the quarry known as a ‘Bearing’. The Doosan Daewoo Excavator is fitted with a strong rock bucket that enables it to loosen and remove the hard shale and mudstone.

Kudos for posting such a useful weblog. Your blog isn’t only informative but also very artistic too. There normally are extremely few people who can write not so simple articles that creatively. Keep up the great work !!
