Comparative Study on Freezing Method and Grouting Method of Shaft Construction Technique in Coal Mines
FENG Xu-hai
Abstract：Freezing sinking method and grouting sinking method are two special shaft sinking methods , these two methods have been successfully applied in Eastern Mining Area in China. There are many significant differences between the two shaft sinking methods ,such as functions ,principles ,time effect ,applicable conditions ,influencing to shaft sinking ,project cost ,and so on. Therefore ,the mature model of freezing upper alluvium and grouting lower bedrock was formed ,and derived the quick shaft sinking technology of “freezing-grouting parallel operation” ,it promoted the development of mine con‐struction technology. While the two shaft sinking methods were applied in Western Mining Area in China ,due to changes in ground water ,soft rock and other geological conditions ,the two methods led to many problems be left in some shaft projects ,the reasons were inappropriate choice of shaft sinking methods and technical parameters. According to strata conditions of Western Mining Area in China and technical characteristics of special shaft sinking methods ,we proposed the ideas and principles to deal with the problems of shaft sinking in Western Mining Area in China ,and introduced the latest techno‐logical advances of freezing sinking method and grouting sinking method based on the success pro‐ject s.
