This research is titled “Proposal for the use of battery-powered LHD equipment as a competitive alternative to diesel equipment in the cleaning process of horizontal underground workings in a mechanized mining operation.“ This study aims to evaluate a proposal for the use of battery-powered LHD equipment as a competitive alternative to diesel equipment in the cleaning process of horizontal underground workings, determining the productive factors, analyzing environmental sustainability and evaluating the operational costs related to LHD equipment. diesel and battery. Likewise, for the comparative evaluation of these equipment, an analysis was carried out through a case study in a mechanized mining unit, with similar characteristics to the Atacocha Mining Unit. The equipment that will be used for the evaluation, under the same working conditions, are the battery-powered LHD (ST7), from Epiroc, and the diesel LHD (R 1300G), from Caterpillar; both with a rated payload capacity of 6,800 kg (4.2 yd3). The results obtained through the case study occurred at three levels: productive, environmentally sustainable and economic. In the productive aspect, it was determined that the battery-powered LHD equipment compared to the diesel-powered LHD equipment, for a hauling distance of 150 m, has a shorter cycle time of 8.23%, and a higher productive performance of 8.98%. In relation to the management indicators, it was determined that battery-powered LHD equipment has an advantage over diesel equipment as in the indicators of mechanical availability, effective use, MTBF and MTTR, obtaining that in the first three it is greater by 0.51% , 10.45%, 4.8%, respectively; on the side of the MTTR indicator, with a result of 12.52% lower than the diesel equipment. In the aspect of environmental sustainability, when the diesel equipment is in operation, the levels of gases are increased compared to battery-powered equipment by 76.63% in CO, 72.45% in CO2, 50% in NO2; Likewise, in the work area of the diesel equipment, a temperature increase of 19 °C is generated, while with the battery-powered equipment there is an increase of 3.5 °C. Finally, in the economic aspect, it was determined that diesel equipment has a lower cost of ownership of 35.28 $/hr, a higher operating cost of 31.24 $ /hr and a higher total cost, including ventilation cost, of 1.63 $/hr unlike battery powered equipment.
