Hammering the Hardest Rock in the World

using my Cat 314e excavator with my NPK gh6 hydraulic hammer to tackle some of the hardest rock in the world, just so you know this hammer weighs 2300lbs, its a good size hammer !

Why does the ground smoke a lot still is there lava still underneath

It smokes white where the rock is really hard, it creates rock dust when I am trying to break it, that's how I know I hit what's called a blue rock vein, its extreamly hard veins in the rock usually running in the direction of the lava flow, its where the lava was really dense and compressed with high pressures, all the lava has cooled long ago, thanks for watching.
