摘要
某改扩建高山矿井通风系统极其复杂,存在通风量无法满足生产需求,井下漏风、风流短路等问题严重,夏季自然风压大,深部平硐反风严重等问题。针对矿井通风系统存在的问题,采用了简化、缩短矿井通风线路,优化主扇运行工况和新增586 m回风平硐主扇,采用充填、密闭等方式隔离407 m以上采空区来控制自然风压等优化措施。采用Ventsim软件建立矿井通风系统三维仿真模型进行网络解算,解算后的矿井总进风量为349.8 m^(3)/s,预期通过采取一系列优化措施后的矿井通风系统可以满足井下生产通风需求。
The ventilation system of a reconstructed and expanded alpine mine is extremely complex.There are some problems in the ventilation system,such as the ventilation volume can not meet the produc-tion demand,the underground air leakage,the short circuit of the air flow,the large natural wind pressure in summer,and the serious reverse wind in the deep adit.In view of the problems existing in the mine ventila-tion system,the optimization measures such as simplifying and shortening the mine ventilation line,optimiz-ing the operating conditions of the main fan,adding the main fan of the 586 m return air adit,and isolating the goaf above 407 m by filling and sealing to control the natural wind pressure are adopted.Ventsim software is used to establish a three-dimensional simulation model of mine ventilation system for network solution.The total air intake of the mine after solution is 349.8 m^(3)/s.It is expected that the mine ventilation system af-ter a series of optimization measures can meet the needs of underground production ventilation.
