Abstract: Roof and surrounding rock need to be supported in the process of roadway drivage, but anchoring and shotcrete supporting was difficult in broken surrounding rock with water spray, and it has a larger effect on suuporting. Before the anchor net spray support, hollow anchoring grouting sealing technology was availabled to prevent the deformation of roadway in roof and larger sections of water spray. The successful application of new technology of hollow grouting in Selian No.2 Coal Mine provides favorable conditions for the anchoring and shotcrete supporting.
