摘　　要：制定有效的井下无轨运输车辆调度策略,是提高地下矿山生产效率和保障生产安全的重要手段。针对地下矿山无轨运输路况复杂、车辆避让困难等特点,分析了井下巷道结构对运输能力产生的影响。在获取井下车辆实时位置与载重信息的基础上,确定了井下无轨运输车辆在不同线路结构下的路权优先原则;以总运输功最小和车辆等待时间最短为目标,构建了基于GA算法和逻辑关系的井下无轨运输车辆调度目标优化模型。采用某矿山井下无轨车辆的实际运行数据,对建立的目标优化模型进行了求解。结果表明:①建立的路权优先原则能够有效降低车辆在非错车段相遇和由此引发安全事故发生的概率,提高了车辆运行效率;②以案例矿山实际运行数据为基本参数,采用GA算法对所建立的总运输功目标函数进行求解,获得了总运输量为4730 t/d时,最小总运输功为2399.21 t·km的最佳路径方案;③在当日运输功最小的基础上,通过逻辑关系对不同出矿方案的车辆等待时间进行求解,得到了不同方案下的车辆具体运输路线及运行时刻,为矿山生产调度提供了最佳车辆调度方案,有利于降低运输成本和提高车辆运行效率。It is an important means to improve production efficiency and ensure production safety to formulate an effective scheduling strategy of trackless transport vehicles in an underground mine.Aiming at the characteristics of the trackless trans-portation in underground mine,such as the complex road conditions and difficult vehicle avoidance,etc.,the influence of un-derground roadway structure on transportation capacity is analyzed.On the basis of acquiring real-time position and loading information of underground vehicles,the right-of-way priority principle of underground trackless transport vehicle under different route structure is determined.For the goal of minimizing the total transport work and the vehicle waiting time,the objective optimization model of underground trackless transport vehicle scheduling based on GA algorithm and logical relationship is constructed.The actual running data of a underground trackless vehicle in a certain mine is used to solve the established objective optimization model,the results show that:①The established right-of-way priority principle can effectively reduce the probabili-ty of vehicles meeting in the non-wrong section and thus cause safety accidents,and improve the efficiency of vehicle operation;②Taking the actual operation data of the case mine as the basic parameters,GA algorithm is used to solve the objective function established for calculating the total transport work,and the optimal path scheme with the minimum total transport work of 2399.21 t·km was obtained when the total transport volume is of 4730 t/d;③On the basis of the minimum transport work per day,the vehicle waiting time of different scheduling schemes is solved via logical relations,and the specific transport route and running time of vehicles are obtained.this provides the best vehicle scheduling scheme for mine production scheduling,which is conducive to reducing transport costs and improving vehicle operating efficiency.
