Rock Blasting Basics. Rock blasting consists of drilling holes in the rock at depths, in diameters, and at spacing so that the ANFO (which is a mixture of Ammonium Nitrate [fertilizer] and Fuel Oil [diesel fuel]) can fracture the rock in a controlled manner. The rock must fracture enough to displace it and break it down to the size of the intended use.

Facts About: Underwater Drilling Blasting

WHAT IS UNDERWATER DRILLING BLASTING? Rock is often encountered in rivers, estuaries, coastal and open waters and can pose an obstruction to various works. Dredging can be done to remove the rock but sometimes the rocks that are too hard to be dredged directly have to be removed with explosives. Underwater drilling and blasting can sufficiently fragment the rock to allow for it to be dredged.
