| Mining area | Shaft name | Time of accident | Fracture conditions |
|
| Xuzhou | Main shaft of Zhang Shuanglou Coal Mine | 1987.8.7 | The shaft wall was fractured, blocks fell, and water seepage occurred in the damaged area to a limited extent. |
| Auxiliary shaft of Zhang Shuanglou Coal Mine | 1987.7.29 | The shaft wall was fractured. The shaft annulus reinforcement was bent. The cage-girder was distorted. A large amount of groundwater instantaneously burst into the shaft. The water inflow was 60.5 t/h, which flooded the shaft and the roadway. |
| Air shaft of Zhangshuanglou Coal Mine | 1992.6.4 | The shaft wall was fractured, and a large amount of material fell down. The shaft wall was moved inward by 300 mm due to the compressive force. The damage was serious. |
| Huaibei | Auxiliary shaft of Linhuan Coal Mine | 1987.7.12 | The concrete in the shaft wall fell in pieces in a ring. The depth was between 200 and 250 m. The reinforcement was exposed and bent backward. The water inflow at the rupture was 1 t/h, and the headframe was displaced. |
| Main shaft of Haizi Coal Mine | 1988.10.6 | The concrete in the shaft wall was spalled, and the reinforcement was exposed and bent backward. Some parts of the shaft wall were underwater, and a cage-jamming accident occurred. |
| West air shaft of Linhuan Coal Mine | 1993.7 | The concrete in the shaft wall fell off in pieces. The depth was between 200 and 250 m. The reinforcement was exposed and bent backward. |
| Auxiliary shaft of Wugou Coal Mine | 2013.6 | Water burst from the connecting-bolt gaps of the cage-guide, which was 256 m from the surface, and the water level increased. Water appeared in two sand holes on the right-hand side of the shaft wall. |
| Huainan | East air shaft of Panyi Coal Mine | 1992.7.27 | The surface of the shaft wall cracked; the maximum width of the crack was 1.3 m and the depth was 100 mm. Water seepage occurred in local areas. |
| Auxiliary shaft of Banji Coal Mine | 2009.4.18 | A large volume of water inrush occurred, with a water inflow volume of 10,000 m3/h. The fan stopped running and the entire mine was flooded. |
| Jining | Main shaft of Baodian Coal Mine | 1995.7.12 | The cage-guide joints were compacted, the pipelines were compressed and bent, and multiple horizontal cracks appeared on the concrete surface. |
| Main shaft of Xinglongzhuang Coal Mine | 1997.6.23 | The cage-guide joints were compacted, the pipelines were compressed and bent, and multiple horizontal cracks appeared on the concrete surface. The vertical reinforcement was bent and exposed. |
| Heze | Main shaft of Guotun Coal Mine | 2015.6.1 | Six pieces of cage-guide on the first compressible shaft wall in the shaft came loose and dropped, resulting in damage to the skip tail rope and the support mechanism at the shaft bottom. |
