- Abstract
- The aim of this thesis is to investigate and evaluate the use of escape filters during the construction phase of tunnels and mines. To achieve this aim three main research methods were used. Firstly, a literature review was produced to evaluate the current research about escape filters and fire safety during the construction phase of tunnels and mines. Secondly, interviews were conducted to find real-world examples of evacuation strategies and escape filter usage. Thirdly, a method to calculate the walking distance while using an escape filter was created and combined with a pre-existing one-dimensional evacuation model. The literature review found that very little research on the use and function of escape filters has been published. The... (More)

Thirdly, a method to calculate the walking distance while using an escape filter was created and combined with a pre-existing one-dimensional evacuation model. The literature review found that very little research on the use and function of escape filters has been published. The interviews concluded that the main evacuation strategy was to either use a vehicle to exit the tunnel or walk to the closest rescue chamber and wait for rescue. The results from the evacuation model showed an increase in possible evacuation distance while using the escape filter. A sensitivity analysis showed that the results were highly sensitive to the reaction time and start distance. Therefore, further studies with escape filters in real fires are needed to validate the results. (Less)
