Optimization design of ventilation system in old mines with complex conditions
Linhuan Coal Mine is an old mine with severe disasters such as gas and natural combustion.After adjusting the mining scope and development method of the mine,to ensure that the mine ventilation system meets the needs of safe production,based on the network solution of the ventilation system,the ventilation system of the mine has been optimized and designed.The design content mainly in-cludes closed west air shaft,new central air shaft,and other aspects.The optimized ventilation system is not only reliable and meets the ventilation needs of the mine,but also achieves the effects of energy conservation,emission reduction,and efficiency improvement.
