Conclusions

  1. 1.

    The use of collapse blasting for constructing rock dams substantially increases the technical and economic indices of the blasting technology of constructing earth dams.

  2. 2.

    The selection of the technology of constructing blast-filled dams is determined mainly by the engineering-geological conditions at the construction site. At present it cannot be confirmed whether the use of loosening blasting promotes an increase of the geological properties of soils forming the body of blast-filled dams.

  3. 3.

    Further investigations of the process of movement of blasted rock down a mountain slope with determination of the volume of moving rock, time, andvelocity (acceleration) for a known degree of slope roughness are required for a more complete comparison of the effectiveness of the two existing technologies of constructing dams by directional blasting. Such investigations also enable determining the possibility of using the Amontons-Coulomb law of friction for describing the movement of large earth masses.
