Abstract
"Incidents and emergencies within underground coal mines can result in severe injuries or even loss of life, particularly due to the hazardous nature of mine explosions. One of the options for the miners to protect themselves from these hazards is to be sheltered in a refuge alternative (RA). However, the literature lacks an analysis of survivability constraints and the structural integrity of RAs when exposed to geomechanical changes and the ability to withstand the impact of coal mine explosions. In this study, based on the utilization and survivability constraints, basic human requirements and the required physical specifications of RAs during the events are analyzed in detail for various countries with their regulations. In the following stages, the built-in place (BIP) RAs with the different designs as NIOSH design example and a structure tested at the Lake Lynn Experimental Mine (LLEM) are analyzed as case studies in numerical analysis using a 3D distinct element code (3DEC). Development and abutment loading conditions with various strata conditions are examined for a coal mine environment. This examination mainly reveals that the changing strata conditions for the development loading scenario are highly affecting the explosion resistivity of the structure with around five times higher deformation in terms of central displacement for 0.1 MPa of maximum overpressure at 0.5 seconds of explosion duration. The analysis also indicates that both the abutment loading conditions are significantly damaging the structure prior to the explosion impact, and the embedded steel structures to overlying strata are crucial to lessen this damage by comparing these two different designs in addition to several explosion scenarios"-- Abstract, p. iv
