Conclusions

  1. 1.

    The higher the impact energy, the lower is the value of the stresses which must be induced in a rock mass being broken.

     
  2. 2.

    The use of high impact energies creates more favorable stresses for the percussion tool.

     
  3. 3.

    In the case of high-energy impact, with increasing hardness of the rock the rate of rock breaking will either decrease very slightly (in contrast with fracture by a cutting tool or roller bit) or even increase.
