| included angle d | Air volume (m) 3 /h) | Distance of air supply |
| 15° | 1112 | 3.3m |
| 10° | 1112 | 3.4m |
| 5° | 1112 | 3.5m |

| included angle e | Air volume (m) 3 /h) | Distance of air supply |
| 15° | 748 | 3.2 |
| 10° | 830 | 3.3 |
| 0° | 995 | 3.5m |
| -10° | 1005 | 3.5 |
| -15° | 1112 | 2.5 |
From simulation results, when the angle e is 0 degree (the plane where the first air deflector is positioned is parallel to the plane where the second air deflector is positioned), the air quantity basically reaches the maximum value, the air supply distance also reaches the maximum value, and when the angle e is-10 degrees, the air quantity can reach the maximum value, but the air supply distance begins to attenuate; when the angle e is-15 degrees, the air quantity is still at the maximum value, but the air supply distance is seriously attenuated, so that the aim of adhering to the wall to horizontally discharge air during refrigeration cannot be fulfilled; when the angle e is 10 degrees, the air quantity and the air supply distance start to attenuate; when the angle e is 15 degrees, the air quantity and the air supply distance are seriously attenuated, and the normal refrigeration efficiency of the raise-boring machine cannot be ensured.
