| Abstract: | The experimental condition of the roof bolting with bar and wire mesh in the gob-side entry in 1222(3) Zhangji coal mine is introduced. With the comparision of the sections of the roof bolting with bar and wire mesh in the gob - side entry and the 29U -type rigid support in the supporting entry, it can be proved that the roof botting with bar and wire mesh is obviously better than the 29U-type risid support. |
