How to start digging?
Craft one of the four types of quarry and put it somewhere. Destroy the quarry block (in Survival mode), to start the process of excavation. Blocks will be gathered layer after layer, you can always stop the process by destroying the Redstone block. The shaft will have a ladder if you want to go down yourself.
