Maintenance Planning in Underground Mining Operations

Organizations should have a clear work description of what a planner’s role is. The role may vary between organizations, mainly due to plant size. Some organizations have combined planners/supervisors. Some have dedicated planners for shutdowns/turnarounds. Many have people with a planner’s title, but no planning. So, how do we figure out a planner’s role?

Since there has been tremendous progress in planning and scheduling in the process industry during the last 20 years, it might be worthwhile to give an overview of the current state-of-the-art of planning and scheduling problems in the chemical process industry. This is the purpose of the current review.

Cutting costs has become a high priority, due to the recent economic conditions. Maintenance shutdowns are a major part of the annual budget at most mills, and are usually a target for cost reduction. Maintenance shutdown costs can be reduced by 30-50 percent from historical levels, with start up after the outage occurring smoothly and predictably. Using simple and effective shutdown management techniques can result in such improvements, creating savings equal to several weeks of additional production each year. This can be done without sacrificing any work, or canceling any scheduled downtime.

Standard Job Plans (SJPs) are the product of the planning process. Work crews that have access to well documented SJPs perform higher quality and more consistent work. Using SJPs, effort isn’t wasted on searching for needed information while in the field. SJPs streamline the planning process by allowing planners to refine past plans instead of starting from scratch for each job. SJPs also support a positive plant culture by providing a mechanism for continuous improvement.

Estimating lays the foundation for planning, scheduling, and management of business critical projects. It is also critical for budgeting, bidding and contracting. Achieving consistent, quality estimates is critical to business success. However, many companies lack systems and procedures to ensure consistency in estimating across the enterprise and easily define, benchmark, and refine corporate estimating standards. The potential long term benefits of instituting an effective solution to this problem are enormous.

World-class organizations would not—could not—succeed without implementing an efficient and effective planning and scheduling process. It’s one of those cornerstone processes that can transform your organization into “Best-in-Class.” Here are some of the pitfalls regarding the deployment of Planners/Schedulers (Planners) that can keep you from getting where you want to be.

Planners struggle too much over developing an accurate estimate for each job. Many managers expect planners to develop perfect time estimates. They may even grade technicians and planners on actual field performance vs. the estimates. As a result, planners agonize over the estimates to the point where they don’t get all the jobs planned; even the ones planned still aren’t “accurate.”
