Enhancing Efficiency and Safety in Iron Ore Mining: Innovative Solutions for Water Management in Conveyor Systems

Abstract

This thesis report explores the critical challenge of water flooding in conveyor belt systems within the iron ore mining sector, with a focus on LKAB, a leading Swedish mining company. The study begins by outlining the significance of addressing water accumulation issues that compromise operational efficiency and safety in mining environments. Through an extensive literature review, the research delves into the history of mining, the pivotal role of iron ore in the global steel production industry, and the specifics of iron ore mining processes and their environmental implications. It further investigates bulk material handling in mining, highlighting the use of tanks, silos, and particularly belt conveyors, which are prone to water flooding, causing significant operational disruptions. The report systematically reviews existing problems associated with current water removal solutions in conveyor systems, critically evaluating their effectiveness and identifying gaps. It presents an analysis of innovative approaches and patents in the field, notably examining JP2000318827Aand KR101500125B1, which propose advanced methods and devices for water removal and moisture separation in conveyor belts. These examinations provide insights into potential improvements and technological advancements that can mitigate water-related challenges in mining operations. Future work suggested by the study includes the design of new products and detailed analysis, leveraging the findings to propose practical, efficient, and sustainable solutions to the issue of water flooding in conveyor belts. The thesis underscores the importance of continued research and development in this area to enhance the durability of mining infrastructure and ensure the safety and efficiency of operations.
