Sustainability in underground mining and geotechnical practices

This research investigates the incorporation of recycled waste materials, specifically tyre rubber powder (TRP) into cementitious grouts used in underground mining. By evaluating the impact of waste materials on the grout's mechanical properties, microstructure, and flow behaviour, this research investigates the feasibility of enhancing the sustainability of mining operations. While the inclusion of waste materials generally leads to a slight decrease in the grout's strength, it also improves its flow characteristics, enabling a reduction in water content. This research aligns with the growing emphasis on sustainability within the mining industry, demonstrating a pathway towards more environmentally responsible practices by minimising waste, reducing reliance on virgin materials, and enhancing the long-term environmental stability of mining operations. This research provides valuable insights for the mining industry, highlighting the potential of utilising recycled materials to improve the environmental performance of underground mining projects without compromising operational efficiency.
