Analysis and Resistance Reduction Optimization of High Negative Pressure Ventilation System with Strong Wind in Gucheng Coal Mine

In order to ensure the safe,reliable,economical and reasonable operation of the ventilation system of Gucheng Coal Mine,the resistance reduction research and application of the large air volume and high negative pressure ventilation system of Gucheng Coal Mine are carried out.A method of simulation research based on the MVIS ventilation simulation system is proposed.The specific method is to first analyze the current situation and existing problems of the ventilation system in Gucheng Coal Mine,and then predict and analyze the optimization and transformation plan of the later ventilation system,and put forward a reasonable optimization and transformation plan,and give corresponding technical optimization measures.
