    Goafs Hazard Analysis and Control Technology of Room Mining in Shallow Coal Seam

    • Based on the field investigation and reconnaissance, prospecting and control scheme compilation, four categories goafs hidden dangers of room mining in shallow coal seam were analyzed, that is, resources safety hidden dangers, mine safety production hazards, surface buildings and structures hazards, ecological and social safety hazards. Merits and demerits, applicable condition of four control technologies for goafs of room mining in shallow coal seam were researched including open stripe, grouting, roof collapse for non-collapse goafs and residual pillar filling for recovery.
