The shape of the complete set of the equipment for ventilation deep career by cascade explosion of a fuel -air mix is proved. The complete set of the equipment includes the basic units and elements: capacity of siphon type, a support for accommodation of charges ВВ, devices of management of undermining and the device of the control.
The model of cascade explosion of fuel-air mixture in the depth of the quarry for the purpose of its ventilation is proposed. Model calculations and experiments confirm the possibility in principle to ventilate a deep pit by the indicated method.
