Evaluation on Underground Refuge Alternatives and Explosion Survivability: a Review

Underground mining environments bring occupational health and safety issues with some severe dangers such as mine disasters like explosions. During such events, miners might escape using main access openings, or find a safe haven like refuge alternatives (RAs) to wait and be rescued and evacuated to the surface. In this paper, RAs are explained with their early and current applications. A classification as permanent and portable is explained depending on the conditions and their abilities. This classification is followed by the utilization and survivability of RAs with the requirements and recommendations of the main mining countries. Based on the utilization and survivability constraints, basic human requirements, waiting for a rescue team, and the required physical specifications of RAs during the events are analyzed in detail for various countries with their regulations. Among these, the specification, resistance to the explosion, is discussed in particular, and the studies in the literature are examined in terms of structural deformation. The highest deformed zones, the beneficiation of reinforcing steel components such as stiffeners, and the simulation approaches are investigated through this review.

Automated summary

This paper focuses on occupational health and safety issues in underground mining environments, specifically discussing the application and survivability of refuge alternatives (RAs) during mine disasters like explosions. The analysis considers the requirements and recommendations of various countries, examining factors such as basic human needs, waiting for rescue teams, and the physical specifications of RAs during such events.
