South Gobi Underground Mass Mining Institute

Geohydrology & Water Management for underground mines

SGUMMI COURSE

Course Summary

This comprehensive course in Underground Mine Water Management provides mining professionals, geotechnical engineers, and hydrogeologists with the applied knowledge and technical skills necessary to understand and assess water-related challenges in underground and cave mining operations. Beginning with foundational hydrogeological principles, participants explore the behaviour of groundwater in fractured and porous rock systems, the influence of pore pressure on stability, and the strategic role water plays in both operational efficiency and mine safety. Core topics include site-wide water management frameworks, dewatering system objectives, water’s impact on blasting and production, and the integration of water management into early mine design and permitting. As the course progresses, participants are equipped to interpret hydrogeological data from monitoring, such as standpipe piezometers, vibrating wire piezometers, packer and slug tests, and cross-hole trials. Emphasis is placed on building accurate conceptual hydrogeological models at mine and district scales, which are used to guide dewatering and grouting strategies. In the final sessions, the course shifts focus to the dynamic hydrogeology of cave mines, covering transient hydraulic property evolution, short-circuiting, preferential flow, and mudrush risk. Case studies from numerous mines are used to demonstrate real-world application of the course principles, educating attendees with a practical understanding of mine water management.

OUTCOMES

Key Learning Outcomes

By the end of the course, participants will be able to:

an expert in a mine
  • Understand the impact of groundwater on mine safety, production efficiency, and slope stability.
  • Identify key components of a site-wide water management system and the goals of operational water control.
  • Develop practical understanding of piezometer use, testing techniques, and monitoring methods.
  • Create and validate a conceptual hydrogeological model to support dewatering and risk management.
  • Differentiate between active and passive water control methods (e.g., pumping vs. grouting/freezing).
  • Design effective dewatering plans for shafts, declines, and production headings using case examples.
  • Predict changes in hydraulic behaviour during cave evolution and breakthrough to surface.
  • Assess the contribution of water to mudrush risk and implement appropriate TARPs and management plans.
  • Apply 1D, 2D, and 3D modelling techniques to simulate cave zone inflows and attenuation.
  • Integrate water balance, recharge events, and geotechnical evolution into predictive hydrogeological models
