In order to meet technical needs and minimize the deformation of tunnel,bolt-grouting supporting program was adopted on analysis of interaction between supporting and wall rock.

In order to reflect the change in deformation of surrounding rocks in soft rock bolt-grouting roadway along with time,we have built the time series prediction model of the deformation of surrounding rock in soft rock bolt-grouting roadway based on the RBF neural network and the data of the deformation observed from the locale.

Furthermore, based on the analysis of physico-chemical component of surrounding rock and the situation of the damaged roadway, the method of adopting strong bolting and shotcreting mesh for the primary support and bolting and grouting for the secondary support is put forwa.

Then the incompact rock block was consolidated to unity with anchoring and grouting in permanent support,and the cohesive strengths and internal friction angles of the surrounding rock were also improved,which make the surrounding rock mass change from soft to hard and no-supported effect to support structure.

At the same time,anchoring and grouting were used jointly to deal with large deformation at the bottom of roadway.

In terms of the destroy of the winch house and winch foundation of the -312 m under-shaft in Xie-Li Coal Mine, the breakage causes of the mare analyzed and the rockbolt cable and rockbolt grouting combined reconditioning technology is applied.
