Abstract
The authors propose a mathematical model of the effect exerted by a blast-induced seismic wave on nonuniform (multi-layer) enclosing rock mass around a tunnel. The developed numerical algorithm implements the Godunov splitting method, and a computer system is constructed. The numerical calculations determine safe drilling and blasting parameters to preserve integrity of underground structures.
