    There is a growing concern for sustainability and the reduction of environmental impact in the mining industry, driving the search for more sustainable practices. It is mentioned that the intensive use of diesel in mining requires exploring more sustainable and less polluting alternatives. This study focused on providing a rigorous and well-founded analysis that will contribute to the understanding of the implications of adopting Liquefied Natural Gas (LNG) as a viable option. The study will provide a comprehensive view of the potential benefits and challenges associated with this transition, enabling informed and evidence-based decision making in the pursuit of more sustainable and responsible mining. In the development of this study, Arena simulation software was used to design a discrete event simulation model that included the mine-specific parameters for the analysis. The fundamental importance of properly defining the mine parameters in the simulation model is recognized. Among these parameters are haule rouds, operational times and speeds, which play a crucial role in the outcome of the analysis. In order to analyze the use of diesel fuel and liquefied natural gas in mining truck operations, five specific scenarios have been defined. These scenarios are designed to analyze and understand how each fuel option affects truck performance. The scenarios are as follows: 100% operation with diesel fuel, 75% operation with diesel fuel and 25% with liquefied natural gas, 50% operation with diesel fuel and 50% with liquefied natural gas, 25% operation with diesel fuel and 75% with liquefied natural gas, and 100% operation with liquefied natural gas. The results show a direct relationship between the level of fuel consumption and CO2 emissions, with significant reductions when using more percentage of LNG consumption and less diesel fuel consumption. In addition, it is determined that variations in fueling time have a minimal impact on fuel consumption, although a decrease is evident when using both types of fuel simultaneously due to the longer loading time. In terms of productivity, it is concluded that loading time and consumption level are critical factors. Reducing fueling time and optimizing fuel type can increase productivity and reduce CO2 emissions, improving the efficiency and sustainability of mining operations.
