A mudrush is a sudden, uncontrolled flow of wet fine particles (mud) into an underground mine that damages equipment, infrastructure, and can even cause fatalities. This project aims to develop cost-effective management and monitoring of mudrush hazards within the at-risk Carrapateena cave mine operated by OZ Minerals. Building on recent technological and numerical advances, a novel experimental–theoretical–numerical approach will be used to simulate mudrush risk based on moisture content, particle sizes, compaction, geological conditions, and seismic energy. Outputs will include a practical framework to boost the safety, productivity, and profitability of caving operations to benefit miners and the broader resources industry.

泥石流是湿细颗粒（泥浆）突然不受控制地流入地下矿井，会损坏设备、基础设施，甚至可能导致死亡。该项目旨在开发具有成本效益的管理和监测高危地区的泥石流灾害。 OZ Minerals 运营的 Carrapateena 洞穴矿以最新的技术和数值进展为基础，将采用一种新颖的实验-理论-数值方法来模拟基于水分含量、颗粒尺寸、压实、地质条件和地震的泥石流风险。产出将包括一个实用的框架，以提高探矿作业的安全性、生产率和盈利能力，从而使矿工和更广泛的资源行业受益。
