Evaluating and Optimizing the Effectiveness of Mining Equipm
发布时间：2021-03-03 20:06
负载装卸（The Load Haul Dump,LHD）设备及其操作环境是采矿业中比较复杂的问题。采矿生产率取决于LHD的操作和采矿环境,包括破碎度,砾石尺寸,导航技术等。确保采矿设备的有效性是采矿业面临的一项巨大挑战,它影响着矿业公司在全球采矿业的竞争优势。传统的导航技术需要大量的基础设施来适应自动操作。从全自动车队开始,自动化的范围逐渐扩大,包括更灵活的解决方案,如以安全为主要目标的半自动LHD机器等。因此,对于采矿业来说,利用其集约化设备进行适当的测量是非常重要的。为了使自动化的好处最大化,必须解决以下几个问题。一是改进维护策略,特别是预防性维护,因为这对于避免意外故障造成的时间损失至关重要。另一个问题是采矿环境的复杂性,外部干扰,如超大巨石、道路维护等,这可能会使整个自动化的投入受到挑战。本文旨在开发一种使用R-studio软件的算法,该算法将科学地用于确定和评估采矿设备的生命周期,并确定和分析整体设备有效性（the Overall Equipment Effectiveness,OEE）以评价采矿设备,并确保优化过程的有效性。研究方法包括文献综述、非结构化访谈以及数据收集等方...
