Conclusions

  1. 1.

    The chief effect on the speed of elastic waves in a rock mass in the ultrasonic range is exerted by the stress in the rock.

  2. 2.

    The stresses level out the effect of the fissures, bestowing on a rock mass properties similar to those of a solid, isotropic, homogeneous body. This confirms the correctness of applying the methods of the theory of elasticity and the mechanisms of a continuous medium to a rock mass.

  3. 3.

    Attempts to assess fissuring by the acoustic method in the ultrasonic range must take into account the stressed state of the rocks.
