| 中文摘要: |
| 矿山进入深部开采,通风阻力日益增大,通风系统需降阻优化.综合选取技术、经济、安全稳定性等指标构建了矿井通风系统降阻优化AHP-FPR综合评价模型.对周源山煤矿通风系统提出了调整网络结构、缩短公用巷道长度、刷大断面积、改变主要角联分支风阻等4种降阻优化方案,并对各种方案进行了网络解算和综合评价,确定了最佳方案. |
| 英文摘要: |
| When mines have entered into the deep resource exploitation, the ventilation resistance will increase, and thus it is necessary to reduce the resistance of mine ventilation. This paper comprehensively selected the indexes of technology, economy, safety and stability to establish the comprehensive evaluation model AHP-FPR of mine ventilation system reduction and optimization. It has also carried out the ventilation parameter network calculation and comprehensive evaluation of four reduction and optimization schemes, such as ventilation system’s network structure adjusting, shortening public tunnel length, enlarging basal area, and changing main diagonal branch wind resistance. Finally, the optimum scheme is defined. |
