基于3DSimOpt3.0的三维通风仿真系统节能优化研究

Research on energy saving optimization of 3D ventilation simulation system based on 3Dsimopt3.0

山西潞安矿业集团慈林山煤业有限公司李村煤矿通过构建三维通风模拟系统,对通风系统进行定性、定量的分析,简化通风系统,发现和解决矿井通风系统存在的问题,确定最优调整方案,使中央风井风量变为19 806 m^(3)/min,西三区回风立井风量变为6 540 m^(3)/min,中央回风井负压由原来的2 148.79 Pa变为1 738.55 Pa,提高了通风方向转换预测、日常通风控制、信息管理水平,保证了矿井的安全作业,使今后的通风系统管理更加方便科学。

Through the construction of three-dimensional ventilation simulation system for Licun Mine of Cilinshan Coal Industry Co., Ltd. in Shanxi Lu ’an Mining Group, the ventilation direction conversion prediction, daily ventilation control and information management level was improved. Therefore, the advanced three-dimensional ventilation simulation optimization system was used to qualitatively and quantitatively analyze the ventilation system, simplify the ventilation system, discover and solve the problems existing in the mine ventilation system. Finally, the optimal adjustment scheme was determined, which made the air volume of the central air shaft become 19 806 m^(3)/min, the air volume of the return shaft in the west three districts become 6 540 m^(3)/min, and the negative pressure of the central return shaft changed from 2 148.79Pa to 1 738.55 Pa, which ensured the safe operation of the mine and made the future ventilation system management more convenient and scientific.
