维修费用往往占采矿工业生产总成本的18～20％,且随着人工和材料价格的上涨,维修费还有占总成本更大百分比的危险。此外,没有有效的维修计划,较之没有计划更有可能使成本暴升。换言之,当生产设备失修时,就得停产,致使没有产品向市场销售。因设备故障所造成损失产量的这种费用,远远超过由人工和材料决定的实际维修 Maintenance costs tend to account for 18-20% of the total cost of the mining industry, and as labor and materials prices rise, there is a danger that repairs will be a larger percentage of the total cost. In addition, the absence of a valid maintenance plan is more likely to escalate costs than without it. In other words, when the production equipment is out of service, you have to stop production, resulting in no product being marketed. This cost of lost production due to equipment failure goes far beyond the actual maintenance by labor and material
