Within the underground mining enterprises, in the event of a fire underground, it is necessary to isolate the mining site or mine workings to protect miners from poisoning by flue gases. To do this, the Mine Ventilation Wall (MVW) is used. Its second purpose is to regulate the air distribution underground, to fence sections not designed for ventilating. This survey describes the design of the MVW new type, which will have a number of competitive advantages in regard analogues existing. The results of mathematical modeling of the MVW properties under different conditions are represented.
