The characteristics of new ejector, produced by Institute of Thermal Physics of Siberian Branch of the Russian Academy of Science, differed from last type of ejectors by presence of aerodynamics lattice, which advancing process of pulse energy disposal from active current to passive directly in diffusion cell, has been shown. The ejector has maximum possible pressure, raised range capability, and low consumption of pressed air. The ejector area of usage in ore and coal mines has been described. Results of exploration tests have been adduced.
