Breaking hard compact materials, such as rock and concrete, is based upon a controlled-fracturing process. A high-pressure foam is used to pressurize a predrilled hole of appropriate geometry. The high-pressure foam is delivered to the bottom of the drilled hole by a barrel inserted into the hole. The barrel includes a seal near the bottom of the hole. By restricting and controlling the pressure of the high-pressure foam to the bottom of the hole, a controlled fracturing is achieved which results in the fracturing and removing of a large volume of material at a low expenditure of energy. The foam-injection method produces almost no fly rock or airblast. The foam-injection method may be used to fracture, remove and/or excavate any hard material such as rock or concrete. The method may be used in either dry or water filled holes and the holes may be in any orientation. The foam injection apparatus is carried on a boom mounted on a carrier. An indexing mechanism allows both a drill and a foam injection apparatus to be used on the same boom for drilling and subsequent high-pressure foam injection.
