摘要
提高矿山资源回采率,减低矿石的贫化损失,可以为矿山企业带来巨大的经济效益和社会效益。以矿业软件为平台,共享地质数据、测量信息、采矿设计等信息,从而实现露天矿反循环钻品位控制数字化管理的工作流程。以某金矿为工程实例,详细介绍了利用三维矿业软件,结合反循环钻取样工艺,建立RC品位控制孔数据库、二次圈定矿体模型、建立块体模型、指导生产作业的步骤和数字化技术,为提高露天开采中矿石的贫化损失控制能力和资源回采率提供了借鉴经验。
The increase of recovery rate and the decrease of di- lution rate can bring great economic and social benefits for mines. Taking mining software as platform, geology database, measurement information, mining design and other information were shared, and the workflow of digital management of reversed circulation drilling on grade control in open pit was realized. Taking a gold mine as an engineering prac- tice, using 3D mining software, combining reverse circulation sampling technology and building RC drilling hole database, orebody secondary delineation and block model were introduced, as well as the procedure of guiding production and digital technique. The study provided reference to reduce the dilution and loss and improve the recovery rate in open- pit mining.
