Assessment of refuge bay designs in collieries

Abstract

The original output of this project was directed at reassessing the survival strategy following colliery explosions and fires. With regard to explosions, problems were experienced with delivering the outputs with regard to strength requirements for refuge bay bulkheads. These problems were resolved during a special meeting held early during 1996 when the scope of the final output was redefined to focus on the characteristics of the explosions that refuge bays could be subjected to in the underground environment and how the Refuge bays would react to these explosive forces
