| Abstract: | The problem of roadway support in weak rock in Jinchuan mining is well known in China. The present situation of the problem is discussed, and it is pointed out that bolt-grouting support is very suitable for the weak rock roadway in Jinchuan mining. The testing study is made on the weak rock roadway with bolt-grouting support in Jinchuan Second Mine. The testing result shows that bolt-grouting technique is reliable, convenient and economic, and should be popularized and utilized in weak rock roadway in Jinchuan mining. |
| Keywords: | weak rock roadway roadway support rock bolt grouting bolt-grouting support |
