Implementing Lean Manufacturing Method to Achieve an Effective Maintenance System in the Mining Company

mining company. It investigates the maintenance process over
digitalization and optimization as a pillar of Industry 4.0. The main
goal of the research in this article was to design an effective
maintenance system for the material and spare parts. The object of
the research was the mining company in Slovakia that focuses on
the maintenance process of mining machines in the frame of a wide
spectrum of mining activities. Economic quantitative methods were
used in solving the research, observation for spare parts, a graphical
method for spare parts layout, and software application. The
relevance of this scientific research was related to the innovation of
the maintenance process with large barriers. We suggested a
document, a record of spare parts, a flow chart for supply, a model
of a maintenance system, and a model of controlling. The
conclusions of this mining company can be recommendations for
other mining companies around the world.
