Análise da influência da infraestrutura de mina na eficiência das operações de lavra em minas a céu aberto

Abstract

This paper discusses the influence of mine infrastructure on the efficiency of mining operations in open-cast mines, with a focus on the geometric, structural, functional and drainage design of mine roads. Through a literature review and a qualitative approach, it was possible to unravel the complexity of the interactions between infrastructure and efficient mining operations. The results highlight the importance of meticulously planning the geometric design of the roads, in line with the mining method and the specific characteristics of the site. In addition, structural integrity, operational functionality and an effective drainage system emerge as crucial elements for the safety and productivity of mining operations. The study reinforces the need for holistic infrastructure planning that considers operational and environmental variables, contributing to the existing literature by reiterating the importance of an integrated view of mine infrastructure. The limitations of the qualitative approach and the literature review are acknowledged, and future research suggests integrating quantitative methods and investigating the application of innovative technologies. The paper concludes by emphasizing the complexity and importance of mine infrastructure planning, serving as a basis for future research aimed at improving mining engineering practices and the operational efficiency of open-pit mines.
