Mining plays a very important role in the economic growth and sustainable development of a country or a region. This sector plays a fundamental role in the economy and brings with it an increase in national reserves, in addition, they contribute to society by encouraging investment and employment, allowing an economic balance. In the present research work, the efficiency of the production plants of a quarry was evaluated using the OEE indicator (Overal Equipment effectiveness). Obtaining as a current result 65%, while the world standard average is 85%, and that of the other quarries of the company is 80%. For the development of the research, the causes that affect the efficiency of the quarry were identified and analyzed. Being the most relevant causes, the jams that occur in the crusher, corrective maintenance, equipment inspection, cleaning of strip glues and concrete supplies. Likewise, based on the causes analyzed, the implementation of the Lean methodology and its TPM and SMED tools is proposed. With the aim of increasing the OEE of the quarry production plants. The implementation of the TPM tool will allow us to reduce downtime for corrective maintenance. Meanwhile, the implementation of the SMED tool allows us to reduce the times of the causes of inspection of equipment, loosening of the crusher, cleaning of tails and supply of concrete. With the implementation of these tools, the OEE will be increased by 23.5%.
