| Abstract: |
| Bolt grouting technology can effectively improve the mechanical properties of roadway surrounding rock and control the deformation of surrounding rock, and has a wide range of applications in underground rock reinforcement and water blocking. Yunnan Tin Group in recent years, with the increase of mining depth, the loose, weathered granite rock excavation often encountered spalling and roof fall, after the excavation, the floor heave deformation phenomenon is serious, especially in the water under the action of the above problem is more prominent, the driving efficiency is very low. In view of the above problems, through the design of the scheme, the development of anchor block material and the field industrial test, the bolt grouting technique has been successfully applied to the reinforcement and water blocking in the underground roadway of Yunnan tin mine. The water blocking efficiency has reached 100%. |
