并联通风巷道断面优化设计的探讨

Discussion on Optimizing Design of Tunnel Section with Parallel Ventilation

文章通过对矿井并联通风巷道掘进费用、维护费用和通风运营费用等综合分析,采用微分极值法,对两(多)条并联巷道通风巷道经济断面的选择提供理论依据,对目前大型、特大型现代化矿井的通风巷道断面优化有很强的实用性和使用价值。

This paper analyzes the tunneling cost, maintenance cost and cost on operation ventilation of tunnel section with parallel ventilation, the selection of economical cross-section of tunnel section with parallel ventilation provides theory by using differential extreme method, which is practical and valuable to optimize design of current large-scale and super-huge type tunnel section with parallel ventilation.
