Abstract Based on the theoretical analysis and testing studies, the relationship between the fracture coefficients of surrounding rocks and the peripheral displacements of the laneway is set up. The theory and method of the grouting bolt are also put forward, which can be used as a instrument of lagged time for directing grouting.Furthermore, the reasonable range of fracture coefficient of surrounding rocksat the beginning of grouting is examined,and the nomogram of the displacement oflaneway profile is determined.
