摘　　要：针对目前煤矿井下排水控制系统自动化控制程度较低,水泵启停控制逻辑不合理,应急处理速度慢等问题。以协调多级排水系统运转、降低系统运行能耗为目的,设计了一种基于动态规划算法的井下多级自动排水系统,通过设置涌水量传感器监测当前出水量的变化速率,结合时段平均出水量作为判断条件,实现启泵数量控制,并运用动态规划算法寻找各级泵房最优控制方法,实现多级排水系统的协同调度。结果表明,该控制系统具备良好的多级协调能力和应急处理能力,能够有效避免溢仓情况的发生;在3种不同排水量情况中,运行能耗分别降低了21%、21%、29%,效果显著。For the current coal mine underground drainage control system automatic control degree is low, pump start and stop control logic is unreasonable, the emergency processing speed is slow and so on problem. With the aim of coordinating the operation of multi-stage drainage system and reducing the energy consumption of system operation, an underground multi-stage automatic drainage system based on dynamic planning algorithm is designed to realize the control of the number of starting pumps by setting the surge water sensor to monitor the change rate of the current water output, combining the average water output of the time period as the judgment condition, and using the dynamic planning algorithm to find the optimal control method for all levels of pumping, so as to realize the synergy of multi-stage drainage system. The results show that the control system has good multi-level coordination and emergency handling capability, and can effectively avoid the occurrence of overflow situations;in the three different drainage situations, the operating energy consumption is reduced by 21%, 21% and29% respectively, which is effective.
