Abstract:The ventilation mode of natural ventilation is used by a gold mine of 1# and 2#, and the ventilation system of 3# adopts the drawing out type. With the increase of mining depth, the problems such as the difficult to control ventilation air volume, dirty wind circulation, short circuit of ventilation are increasingly prominent, which seriously affected the safety of mine production. Based on these issues, the type of pressurized ventilation is adopted in 1# and 2# ventilation system, and the ventilation system of the 3# still uses the drawing out type. At the same time, the corresponding ventilation network is optimized, and the location of the main fan layout has been adjusted. According to the ventilation network of Optimization, the ventilation system of mine air flow and ventilation resistance are estimated. Therefore, the reasonable ventilation equipment is selected, the ventilation management scheme of this gold mine have perfected, provided the safeguard for mine safety production.
