A bit of forceful excavating

We have quite a bit of blasting to get this site ready for a new lake home. This is a small blast that I happened to catch as I stopped in to the site today.
Here the blast mats are in place to (hopefully), keep any rock from flying. We are just knocking down this knob a little bit and then they need to turn around and cut into the back ledge-rock wall with two or three more blasts.

 

 

Blast mats in place

I thought I had a better shot of it but maybe this is close enough...
