Anything interfering with the strength of the compressive stress waves (7) during operation such as. blank-firing (free-running) or prying with the tool, can lower breaker performance and cause tool. fatigue. The breaker must be at a 90Â° angle to the face of the rock. (D)Blank-firing. Blank-firing the breaker without the tool pressing on a rock causes the energy that normally travels. out the tool into the rock (8), to impact the retainer pins (9) and front head causing excess stress to. these components.
The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment. Gradually, the sediment accumulates in layers and over a long period of time hardens into rock. Generally, sedimentary rock is fairly soft and may break apart or crumble easily.
