通风井巷断面优化在设计中的应用

Application of Cross-Section Optimization for Ventilation Roadway to Designing Process

断面优化是矿井通风系统优化的重要部分,只有当断面最优或接近最优时,巷道的掘进费、维护费和通风费的总和才能达到最小;建立井巷断面优化数学模型,可以得到在资金时间价值影响下的最优断面,以达到节能降耗的目的。

Section optimization is an important part of the optimization of mine ventilation system, Only when the section is optimal or near optimal, can the sum of tunneling fee, maintenance fee and ventilation tunnel fee be minimum. Establishment of the optimization mathematical model of roadway cross-section can obtain the optimal section under the influence of the time value of money , and achieve energy saving objective.
