Abstract

To solve the support problem of surrounding rock roadway in deep mine with high stress, based on the geological conditions of the third level roadway in Haizi colliery,it discussed the factors affecting the surrounding rock deformation first, and established the numerical simulation model of roadway and studied the failure characteristics and deformation mechanism of the surrounding rock in this paper. The results show that when roadway being dug, the high stress environment led to serious deformation and failure to the surrounding rock, so the surrounding rock need to play a supporting force by itself. According to the deformation characteristics, the supporting scheme and parameters were determined and applied in field test. The monitoring results show that the full section bolt-grouting could effectively limit the harmful deformation of the roadway , and it successfully maintains the stability of roadway .
