Distribution of Side Abutment Stress in Roadway Subjected to Dynamic Pressure and Its Engineering Application
Table 5
Factors affecting the distribution of the side abutment stress.
| Influential factor | Position of the peak side abutment stress | Peak value of the side abutment stress | Scope of influence of side abutment stress | Stress concentration coefficient |
| Coal strength | Inverse ratio | Minor influence | Minor influence | Minor influence |
| Breakage position of the main roof | Minor influence | Minor influence | Minor influence | Minor influence |
| Depth | Direct ratio | Direct ratio | Minor influence | Inverse ratio |
| Immediate roof strength | Inverse ratio | Direct ratio | Minor influence | Direct ratio |
| Immediate roof thickness | Inverse ratio | Inverse ratio | Minor influence | Inverse ratio |

Note: the position of the peak side abutment stress refers to the distance of the side abutment stress to the gob.
