You'll need drilling equipment to start the process. This equipment includes an excavator tool that comes with a rock breaking tool attached to the drill. You can also use the drill attachment to cut holes directly into the rock that you want to break down and excavate. Your blasting contractors then fill these cut holes with explosives.
