摘要/Abstract

摘要： 乌龙泉矿东区采场内矿石出矿品位波动较大、低品级矿石难以回收，而采场内配矿效率低、准确度不高，不利于矿山高效稳定生产。采用3D-Mine构建乌龙泉矿东区采场矿石品位分布数字模型，将品位分布数字模型样品数据与钻孔数据库进行对比分析，验证了模型品位输出的可靠性。提出了品位分布数字模型应用于实际工程的基本流程为模型上圈定开采计划线—开采计划线内矿石产量和品位统计—爆破区域划分—配矿方案制定—现场开采及配矿工作，并应用于乌龙泉矿东区采场的实际开采和配矿工作中。结果表明：品位分布数字模型可以简单方便地统计任意开采区域内矿石的产量和品位，有效地指导工作面的推进和爆破区域的划分；通过统计各爆堆矿石的产量和品位，可以提高现场配矿的效率和准确性，促进采场低品位矿石的回收、出矿品位稳定及矿山高效稳定的生产。

Abstract: he considerable fluctuation of mined ore-grade and the difficulty of recovering low-grade ore are existing in eastern stope of Wulongquan Mine.It is unfavorable to guarantee the efficient and stable production due to the low ore blending efficiency and low accuracy in the stope.3D-Mine is used to construct an ore grade distribution digital model in eastern stope of Wulongquan Mine and contrast the sample data in the model with borehole database to verify the reliability about ore grade output result.The basic processes of this model in actual engineering are proposed,showing as：Delineate a mining scope in the model-count the ore grade and yield in the plan-divide blasting area-formulate ore blending scheme- field mining-ore blending.And then the model is applied to actual mining and ore blending work in eastern stope of Wulongquan Mine.The result indicates：it is convenient to count the ore yield and ore grade by using this model.The ore grade distribution digital model can effectively guide the propulsion of work surface,divide blasting area,count each exploded ore yield and ore grade,improve the efficiency and accuracy in field ore blending,promote the recovery of low-grade ore,ensure the stability of mined ore grade,and facilitate the high efficient and stable production in mine.
