摘　　要：为提高地下矿山单车道主斜坡道的运输效率与安全性,解决因多车型混合车流共存导致的通行能力不足、交通拥堵及安全隐患等问题,提出了一种基于跟驰理论的通行能力量化方法,构建了包含运矿卡车、无轨人车、材料车等5类车型的混合车流模型。模型综合考虑了车型组合概率、制动性能差异及错车道间距等关键参数,修正了安全行车间距计算模型,并量化了平交路口、路侧干扰对通行能力的折减效应。以某矿山实例验证表明:修正后的基本通行能力为19 pcu/h,矿(废)石年实际可运行能力达60.978×10^(4)t/a;当错车道间距从200 m缩短至100 m时,运行能力提升至96.282×10^(4)t/a;其余车辆通行次数不变时,斜坡道矿(废)石实际可运行能力与无轨人车通行频次呈负相关。结果表明,车型比例与错车道间距对斜坡道运行能力具有显著非线性影响。该模型为矿山斜坡道设计与无轨设备调度提供了定量化决策依据,可支撑矿山运输系统的高效化与智能化升级。To enhance transportation efficiency and safety in underground mine single-lane main ramps,this study proposes a car-following theory-based traffic capacity quantification method addressing mixed traffic flow challenges.A heterogeneous vehicle model incorporating five vehicle types(including ore trucks,trackless personnel transport vehicles[TPTV],and material transporters)was developed.The model integrates critical parameters such as vehicle composition probability,braking performance variance,and passing bay spacing.Significant improvements include an optimized minimum safe headway calculation model and quantified capacity reduction factors for intersections and roadside interference.Field validation at a working mine demonstrated:①A revised base capacity of 19 passenger car units per hour,translating to an annual ore/waste transport capacity of 609780 t/a;②Capacity enhancement to 962820 t/a when passing bay spacing decreased from 200 m to 100 m;③Inverse correlation between TPTV frequency and ore transport capacity under fixed trip numbers of other vehicles.Sensitivity analysis revealed nonlinear relationships between vehicle mix ratios and passing bay spacing on ramp capacity.This methodology provides quantitative decision-making support for ramp design optimization and trackless equipment scheduling in intelligent mine transportation systems.
