煤矿通风系统的优化分析及应用实现

he existence of a short pause during the conversion between motors will lead to underground coal mine gas outburst in the coal mine ventilation system .Now the paper proposes to add a louvered air damper at the top of the two wind tunnels with combination of actual facts, which is realized that keeping essentially the same amount of wind during the process of conversion underground that also means non-stop conversion; then the non-stop action systems process is proposed from perspective of the draught fan system and PLC control system network. Such programs have been successfully used in several subsidiary mine of Pingdingshan Group, and it has proved the feasibility and practicality.
