This article addresses the issues of unreasonable water scheduling and high costs in coal mine shafts, proposing a hierarchical optimization scheduling strategy. Taking the water quality and quantity of a certain mining area in Inner Mongolia as the research object, it designs the objective function with the highest reuse efficiency and the lowest reuse cost of mine water resources, and establishes the constraint conditions of water quality and quantity for each water-using unit. In response to the problem that traditional genetic algorithms are prone to local optima, an adaptive autobiographical operator is proposed and improved based on Metropolis principle of simulated annealing algorithm. The improved algorithm is applied to the calculation of the scheduling model, and the results show that the recovery cost in the heating season is reduced by 66779.36 CNY/month, a decrease of 10.34%; the recovery cost in the non-heating season is reduced by 61469.28 CNY/month, a decrease of 9.91%. At the same time, the heating season and the non-heating season have reduced by 136.99 h/month and 154.52 h/month respectively, significantly reducing the recovery cost and time.
本文针对煤矿井筒水调度不合理、成本高的问题，提出了一种分层优化调度策略。以内蒙古某矿区的水质和水量为研究对象，设计了矿井水资源回用效率最高、回用成本最低的目标函数，并建立了各用水单元的水质和水量约束条件。针对传统遗传算法容易陷入局部最优的问题，基于模拟退火算法的Metropolis准则提出并改进了自适应自传算子。将改进后的算法应用于调度模型的计算，结果表明，供暖季回收成本降低了66779.36元/月，降幅为10.34%；非供暖季回收成本降低了61469.28元/月，降幅为9.91%。同时，供暖季和非供暖季分别减少了136.99小时/月和154.52小时/月，显著降低了回收成本和时间。
