基于采场配矿技术的乌龙泉矿露天采场工作面布置优化

乌龙泉矿露天采场内矿石品级种类较多，部分低品级矿石不能直接满足后续生产加工要求而堆积于采场内部，影响采场的有序推进及矿山生产能力的提高。采用线性规划法建立配矿模型，构建适用于当前乌龙泉矿露天采场内低品级矿石的配矿技术方案；基于配矿技术方案，对乌龙泉矿露天采场的工作面布置进行优化；将配矿技术方案及优化后的工作面布置方式应用于乌龙泉矿露天采场的生产计划中。工程实践表明：采场内配矿技术方案充分利用采场内部矿石参与配矿，有利于低品级矿石资源利用率的提高及配矿成本的降低；工作面布置优化后的乌龙泉矿露天采场能够有效地实现配矿方案在生产中的应用，解决低品级矿石的开采问题，促进采场的有序推进，提高矿山的生产能力及作业效率。

Optimization of Working Face Arrangement on Wulongquan Mine Based on Ore Blending Technology in Stope

There are many types of ores with different grade in Wulongquan open stope，and parts of low-grade ores are accumulated inside the stope since it can not meet the requirements of the follow-up production and processing directly.The accumulation influences the orderly propulsion of the stope and the improvement of the mining production.The linear programming theory is adopted to build the ore blending model，and find the proper ore blending technical solutions for the low grade ore of Wulongquan open stope.The working face arrangement on Wulongquan Mine is optimized based on specific ore blending technical solutions.The optimized working face arrangement with technical solutions is applied to production plan of Wulongquan Mine.Engineering practices show that the specific ore blending technical solutions take full advantage of the internal ores to participate in ore blending，which is helpful to improve utilization of the ow-grade ores and reduce the cost of ore blending.The specific ore blending technical solutions can be effectively achieved in Wulongquan open stope after the working face arrangement has been optimized.Therefore，the optimization is helpful to recover the low grade ores，promote orderly propulsion of the stope and improve the production and operational efficiency of the mine.
