Thanks for the replies. I will look into the blasting mats. I've seen the Youtube videos where they wrap the charges in a fabric that looked like woven geofabric and chain link fence.

[QUOTE=clansing1;13915Sometimes there are rocks that are relatively close to surrounding buildings.

I was wondering what to use to cover the rock to prevent a projectile from flying and hitting something.

Most jobs I am on where blasting is performed either in close proximity to buildings or roadways use blast mats made from recycled tires.
Heavy yes, but very dense and able to contain the effects of the blast and debris very effectively.

Blast Mats or old conveyor belts that are 1 Ply or thicker should be sufficent. When we shoot a building each column is covered with mafari fabric and chain link fence.

Occasionally we are asked to blast limestone rocks that are in the ground and in the way of an excavation. Sometimes there are rocks that are relatively close to surrounding buildings.

I was wondering what to use to cover the rock to prevent a projectile from flying and hitting something. I was wondering if a heavy reinforced tarp would minimize a projectile. By putting a smaller charge we minimize the projectiles, but once in a while a blast will be a little stronger than we need and you will have some projectiles.

Thanks in advance.
