FIELD: mining.
SUBSTANCE: at least two protective partitions are installed in cascade serially one after another on the way of shock wave motion, at the same time one of protective partitions is arranged as perforated, and the other one - as inflatable. One and more perforated partitions are designed to weaken highly intensive shock waves with pressure reduction at shock wave front from 1.6 MPa to 0.2 MPa, and the last inflatable partitions is designed to protect against low-intensive shock waves with pressure reduction at shock wave front from 0.2 MPa to 0.006 MPa.
EFFECT: invention makes it possible to increase efficiency of blast shock wave weakening and suppression, safety in salvage and mine-rescue operations, and near blasting works, and protection of well operators and engineering structures.
