Conclusions

  1. 1.

    The authors obtain the dependence of the LLR of blast-hole charges acting on an unbounded free surface on the acoustic impedance of the rock, the type of explosive, the size of the charge, the blast-hole efficiency, and the quality of rock crushing.

  2. 2.

    The theoretical values of the LLR agree well with experiment.
