    • Abstract
  • The following technology, including using the technology of multi-angle revolving mining at the fully-mechanized caving face to raise recovery ratio and reduce the coal loss in goaf; using double anti-network joint strengthening support fire protection technology to cement soft rock, strengthen rock strength and improve the bearing capacity of the supporting structure, control roadway deformation and reduce air leakage;using three-dimensional pressure injection composite retarding foam to put out the coal spontaneous combustion hidden fire behind the support or at the height of goaf fissure, are used to prevent fire disaster in high gassy extremely soft and easy spontaneous combustion coal seam under complex geological conditions and ensure safe and efficient coal production.
