Abstract

Abstract: The mining way in Shadunzi coalmine is fully mechanized caving mining of thick coal seam. The spontaneous combustion period of 4# coal seam is short, which makes working face recovery time tight. Comprehensive plan including strengthening roof control of termination, hydraulic support as shield supporting recovering space and comprehensive measures against fire of nitrogen injection with inhibitor injection, yellow mud Colloids injection and mud grouting was carried out. Only 25 days were used to complete the whole recovery of N4002 working face, which provided experience learning for recovery of followed or similar working faces.

Key words: hick coal seam, easily spontaneously combustion, shield support, fire prevention and extinguishing, quick recovery
