Mining companies need to implement models which allow to develop a dynamic and agile mining process, based on the statistics analysis. OMEE (Overall Mining Equipment Effectiveness) is a methodology that allows to study the effectiveness and the technical replacement time of mining equipment through four steps: i) Acting; ii) Observing; iii) Evaluating; and, iv) Planning; analysing four vital parameters: i) Technical availability rate; ii) Mechanical availability rate; iii) Utilization; and, iv) Productivity index. The case study side was an open pit coal mine located in the North-West of Spain. In this paper, the performance of six drilling rig equipment has been analysed for twelve years. The research uses the OMME method, to assess the effectiveness of the mining equipment fleet and to estimate the technical replacement time.
