【 摘 要 】

On the basis of experimental data, a technological scheme to separate large-size granite blocks from a rock mass by an impact method is proposed, the process parameters of block preparation for separation are verified by physical modeling, and a rock-breaking tool is proposed; the dependence of the main crack length vs. impact parameters is determined.
