Resumen

In this research, 10 formats are proposed as a single instrument, for taking mining cycle times based on the principles of the value chain map tool. As part of the methodology, we applied the 10 proposed formats in time recording, we analyzed the productive, contributory and non-contributory times, for this we used the Ishikawa diagram that shows us which activities have the greatest impact on low productivity in the horizontal excavations (Mining Cycle) later the mapping of the current state was carried out, finally the time efficiency was processed and calculated. To validate the results, we applied the proposal in the Esmeralda mining company, in its El Teniente mine for 4 months. As a result, we revealed that from a total cycle time of 22.85 hours: the productive time was 13.22 hours, the Contributory time was 4.53 hours and non-contributory time was 5.11 hours. We also revealed that the activities that show the lowest performance are: ventilation, marine loading, coining and drilling. The final conclusion is based on the contribution of the 10 formats and is applicable to underground mining companies who can use the 10 proposed formats to analyze productive, contributory and non-contributory times, and then take corresponding actions.
