Abstract: This paper introduce the characteristics and regularties of roadway deformations,such as noise,rockfall,floor heave,support torsion and so on,occurred in underworkings,which are resulted from the blocking up water grouting in East Air Shaft of Xieqiao Mine Based on the analysis it is considered that the roadway deformations are related to the grouting pressure,the vertical distance of grouting interval to the roadway,the development degree of Karst fractures in grouting interval,total injection amount,and rock mechanical natural and loosened ring range of country rocks The grouting measures used to decrease the roadway deformation degree are put forward
