矿山设备作业条件恶劣,使用周期长,磨损严重而且故障多,维修和保养费用高。如何根据矿山设备的磨损情况,对其所应采用的修理级别(如小修、中修、大修和报废更新等)和修理周期进行优化决策,具有重要的技术经济意义。 关于设备维修策略,国内外有关方面已经进行了多年研究,取得了很多成果,但最基本的优化策略为:依赖于时间的维修策略和依赖于状态的维修策略。当设备运行到规定的时间时,就进行修理或更换,称为定时维修策略。这也是目前我国矿山企业的设备修理制度的出发点。这种修理制度是保证设备经常处于完好状态的一种组织技术措施,
Mining equipment operating conditions harsh, long life cycle, serious wear and tear and failure, repair and maintenance costs. How to optimize and make decision on the repair level (such as minor repair, intermediate repair, overhaul and scrapped renewal, etc.) and repair cycle should be based on the wear status of mining equipment, which has important technical and economic significance. About equipment maintenance strategy, domestic and foreign parties have conducted many years of research and achieved many results, but the most basic optimization strategies are: time-dependent maintenance strategy and state-dependent maintenance strategy. When the equipment runs to the specified time, repair or replacement, known as the timing maintenance strategy. This is also the starting point of the equipment repair system of our country’s mining enterprises. This repair system is to ensure that equipment is often in good condition an organizational technical measures,
