# Mine Fire Behavior under Different Ventilation Conditions: Real-Scale Tests and CFD Modeling
## 3 Results and Discussion
### FDS Results  
Results obtained in the experiments and the FDS model are detailed and compared below. The five scenarios depending on the fuel load and door opening are gathered in Tables 5 and 6. As previously mentioned, there were three temperature control points at different heights in each section (P1: 2 m, P2: 1 m, P3: 0.5 m). Figure 14: Evolution of the temperature along the drift at different heights; scenario 5. Figure 13: Evolution of the temperature along the drift at different heights; scenario 4. \begin{table}
