摘　　要：随着开采深度的增加,井下通风系统变得越来越复杂,矿井通风的管控成为难题。为建立金川二矿区的通风仿真与优化系统,在采用基点法对大量测点进行通风阻力测定的基础上,对矿井通风的难易度和不同季节空区空气密度与自然风压对通风系统的影响进行比较分析。运用iVent三维软件建立了二矿区通风系统三维数字化模型,对三种通风方案进行仿真模拟,解算结果表明,三种通风方案的总风量分别增加了150 m^(3)/s、130 m^(3)/s和20 m^(3)/s,从改善上盘运输巷道排尘效果、提高通风能力的角度推荐方案一为最佳方案,这一先仿真验证后实施的工作流程大大降低了实施成本,并提高了通风系统的可靠性和安全性,可供矿山通风系统优化和调控借鉴参考。With the increase of mining depth,the underground ventilation system is more and more complex,and the control of mine ventilation becomes a difficult problem.In order to establish the ventilation simulation and optimization system in No.2 mine of Jinchuan,based on the determination of ventilation resistance of a large number of measuring points by base point method,the influences of mine ventilation difficulty,air density and natural wind pressure on ventilation system in different seasons were compared and analyzed.Using iVent three-dimensional software,a three-dimensional digital model of the ventilation system in this mine was established,and three ventilation schemes were simulated.The calculation results show that the total air volumes of the three ventilation schemes increase by 150 m^(3)/s,130 m^(3)/s and 20 m^(3)/s respectively.From the perspective of improving the dust removal effect of the hanging wall transportation roadway and improving the ventilation capacity,the first scheme is recommended as the best scheme.This workflow that simulation and verification are adopted before implementation can greatly reduce the implementation cost,and improves the reliability and safety of the ventilation system.The study can provide a reference for the optimization and regulation of mine ventilation system.
