In a surface mining operation the unscheduled downtime due to hose can reach up to 37% of the entire unscheduled downtime for a prime mover hydraulic shovel. Reliability Based Maintenance Programs are more effective at improving fleet availability and Total Cost of Ownership. In this regard, correct process management is a fundamental building block of any successful machine reliability centered maintenance program. This can be expressed as well as the correct management of the application of the machine components, the quality and capability of the human resources involved, the comparative acquisition costs of those components and more importantly the comparative operational performance of those components. The main objective is to quantify the economic value that a reliability centered component maintenance program will bring to the operation in increased safety, machine availability and productivity, environmental compliance and total cost of ownership. This paper will present what this program, called Hose Management Program, looks like for flexible hose assemblies, its applications and the value that it has brought to some mine operators around the world.
