Abstract
Anchor bolt and grouting combination supporting technology has both advantages of bolting support and can use grouting fissure filling surrounding rock fracture, blends anchoring, hole sealing, grouting technology for a whole, to the rock mass anchor external and grouting inside, bolt-inject form a multilayer effective combination arch and bearing load together. Anchor bolt and grouting technology adopted for extremely unstable roadway in Qinan Coalmine, control of roadway deformation successfully, and maintain roadway stability.
