Аннотация

A numerical simulation of the wave distribution along a mine with permeable barriers located in it was carried out within the framework of the equilibrium inviscid setting and without taking into account chemical reactions. The configurations of obstacles with different permeability indices along the length of the working were studied; the porosity of the obstacles varied in the range from 0.2 to 0.8. With an increase in the free cross-section of the barrier (porosity), the load can additionally be reduced, however, barriers with high permeability reduce the efficiency of the barrier, which is confirmed by the increased pressure drop on the shock wave front after it passes the barrier.
