Abstract
This thesis investigates the appropriateness of the room-and-pillar mining system, focusing on pillar recovery at Zhomart Mine, a complex orebody in Kazakhstan's Karaganda region. Given the mine's unique geological characteristics, this study evaluates whether traditional room-and-pillar mining remains suitable amid concerns over subsidence and mine stability. Utilizing the University of British Columbia (UBC) Mining Method Selection Wizard and Rocscience's RS3 for numerical modeling, this research assesses alternative mining methods, particularly Cut & Fill and Sublevel Stoping, against the current room-and-pillar approach.
The findings indicate that the room-and-pillar method, while traditionally favored for its simplicity and cost-effectiveness, ranks lower in suitability due to the mine's geotechnical challenges. Simulations predict significant subsidence and compromise structural integrity following pillar recovery, supporting a transition to more adaptive mining strategies. The thesis advocates for Cut & Fill and Sublevel Stoping, which provide greater control over ground subsidence and enhance operational safety and environmental sustainability.
This comprehensive study not only underscores the need for a systematic reassessment of mining strategies in light of evolving geological insights but also contributes to the broader discourse on sustainable mining practices. The thesis concludes with recommendations for "Kazakhmys" to undertake an economic evaluation, considering the long-term benefits of adopting more suitable mining methods that align with the mine's operational and environmental goals.
