Herramientas de Lean Manufacturing aplicada a la S.M “Oro Inca” perteneciente a la Concesión Minera Shyri código: 101203, ubicado en la provincia del Azuay

Abstract

In Ecuador, mining contributed 1.6% of the GDP; however, considerable untapped potential was identified due to empirical operating practices and lack of standardization in mining processes, which resulted in unsafe work areas, loss of time in work cycles, waste, bottlenecks and economic losses for mining companies. Therefore, this study aimed to apply and implement Lean Manufacturing tools in S.M. "ORO INCA", belonging to the mining concession Shyri code: 101203, located in the province of Azuay. As a main objective intended to improve processes through a mixed methodology and a randomized study population. Improvement models were implemented and maximized the performance of equipment and machinery through proven methodologies, thus standardizing processes and procedures, minimizing operational risks and improving safety in the workplace, crucial aspects for mining productivity. In addition, by analyzing the value chain map, a high working daytime was identified, as the productive time per shift was 10 hours due to these deficiencies. After the implementation of Lean Manufacturing and a new VSM, it was planned to reduce the working day to 8 hours, complying with current regulations. In conclusion, the application of Lean Manufacturing Tools allowed identifying, improving and reducing time cycles in processes and operations that presented defects such as waste, dead times, repetitive activities, deficient tools and inadequate procedures. These aspects directly affected the operations cycle, as a result of the delays in the production line and additional economic losses.
