摘要：The article describes the ventilation schemes of the potash mine production units, in which, due to the action of natural draughts (thermal depressions), as well as the use of portable mine brattice (MB), safety and energy efficiency of mining operations is increased. The design and test results of a new type of mine brattice capable of quickly and reliably isolating a mine site from the passage of "excess" air (normal ventilation mode) and flue gases (emergency ventilation mode) are given.
