Maintenance Planning in Underground Mining Operations

About 25% of a Planner’s time should be spent in the field, assessing and “scoping” maintenance work. To make this time as useful as possible, a good “planner’s tool kit” is essential. A good planner’s tool kit should contain the following items, all in convenient package, such as a light-weight tool belt. Or we like a safety vest with lots of pockets. And, of course, all the required personal safety equipment and a cell phone or pager. As Maintenance’s “information managers”, planners should be easy to contact.

"Listen: I’m a mechanic, not a clerk. Do you want me to do the work OR fill out these work orders? If I wasted all that time filling in those silly blanks on your paperwork I’d never get caught up! Besides, I don’t know why we need ‘em anyway. Let’s just do the work like we’ve always done.” Sound familiar? Maintenance work orders are often seen as an extra burden to the maintainers as well as those who are requesting the work to start with. “Paperwork. Needless paperwork. That’s all it really is anyway. I just want to call the mechanic and get this work done fast!” But without work order history, the maintenance organization is at risk and equipment problems will likely worsen.

The work process we call maintenance planning can almost always be improved in any given mill or plant. In fact in most plants we visit maintenance planners don’t plan. Planners do all kinds of tasks except work order planning.

Companies often ask if maintenance planning and scheduling will work if they have a decentralized maintenance organization. Yes, it will. In fact, they need planning and scheduling just as much as a centralized shop. Let's review why.

Planned maintenance is a maintenance concept developed over a span of time, and is made up of numerous functions, all designed to compliment each other. Planned maintenance, then, is a maintenance program designed to improve the effectiveness of maintenance through the use of systematic methods and plans. The primary objective of the maintenance effort is to keep equipment functioning in a safe and efficient manner. This allows production to meet production targets with minimum operating cost.

Too many organisations neglect the benefits of a clearly defined prioritisation system. Even when they realise the importance the focus is invariably at a department or functional level. I have seen organisations where there are up to three or more prioritisation systems. None of which are inter-related. Along with work order classification, failure coding and integration with business processes, this is one of the key determinants of a maintenance systems future operation.

All of the work of backlog management, planning and priority targeted capacity scheduling are focussed on efficient execution. To ensure that the tasks that need to be done, as per the true requirements of the plant, are done in a timely manner with as little waste of human and material resources as is possible.
