摘　　要：为解决随着工作面推进通风线路延长、局部断面面积减小所导致的风量不足、风阻分布不合理等问题,结合煤矿实际情况提出了通风系统安全的综合评价指标体系,对所存在的通风问题进行综合分析,提出相对应的优化改造方案,并通过所构建的指标体系对不同优化改造方案的综合量化评价值进行对比,最终优选出最佳改造方案。In order to solve the problems of insufficient air volume and unreasonable distribution of wind resistance caused by the extension of ventilation lines and the reduction of local cross-sectional area as the working face advances,a comprehensive evaluation index system for ventilation system safety is proposed based on the actual situation of coal mines.A comprehensive analysis is conducted on the existing ventilation problems,and corresponding optimization and transformation plans are proposed,and by comparing the comprehensive quantitative evaluation values of different optimization and renovation plans through the constructed indicator system,the best renovation plan is ultimately selected.
