摘　　要：大冶铁矿正在进行-270 m中段转至-360 m中段的接续开采工程,由于采切工程滞后,-360 m中段投产初期采场生产能力不足,难以达到4320 t/d的设计产能,而设备调度优化和工序衔接优化是解决产能不足的重要措施。根据分段凿岩阶段出矿嗣后充填采矿法的特点,分析采切、凿岩、装药、爆破通风、出矿等工序的衔接关系,基于大冶铁矿-360 m中段各采场分布、回采工序、回采设备现状,对采场回采设备调度进行优化,并运用遗传算法(Genetic Algorithm,GA)求解出-360 m中段最高效的设备调度计划。结果表明:在设备调度优化(单目标优化)条件下,最短回采总时间为6336 h,首采采场生产能力达到3782 t/d;通过进一步优化工序衔接(双目标优化),减少了回采工序时间间隔,提高了设备的使用效率,最小回采总时间缩短为4250 h,实际工作总时间减少了1977 h,降幅为27%,首采采场生产能力达到5189 t/d,综合生产能力超越其目标值的20%,有助于解决大冶铁矿在当前采切滞后的状态下产能不足的问题。Daye Iron Mine is carrying out a continuous mining project from-270m middle section to-360m middle section.Due to the lagging of the-360m middle section mining and cutting project,the initial production capacity of the-360m middle section is insufficient,making it difficult to reach the designed production capacity of 4320t/d.Equipment scheduling optimization and process connection optimization are crucial measures to address the issue of insufficient production capacity.According to the characteristics of sublevel rock drilling stage ore subsequent filling mining method,the connection relationships among mining and cutting,rock drilling,charging,blasting ventilation,ore drawing were analyzed.Based on the distribution of stopes,mining process,and current mining equipment status at the-360m middle section of the Daye Iron Mine,the mining equipment scheduling in the stope was optimized,and the Genetic Algorithm(GA)was then used to solve the most efficient equipment scheduling plan for the-360m middle section.The results indicate that under the conditions of equipment scheduling optimization(single-objective optimization),the shortest total mining time is 6336hours,and the production capacity of the first stope reaches 3782t/d.Through further optimizing the process connection(dual-objective optimization),the time interval of the recovery process has been reduced,the efficiency of the use of equipment has been improved,the minimum total mining time has been shortened to 4250hours,and the total actual working time has been reduced by 1977hours,with a decrease of 27%.The production capacity of the first mining stope reaches 5189t,and the comprehensive production capacity exceeds the target value by 20%,which is helpful to solve the problem of insufficient capacity of Daye Iron Mine in the current state of lagging mining and cutting.
