Abstract：Aiming at the intense expansion of coal feeding chamber floor for 214 coal bunker affected by water in Xiashijie Coal Mine, the wall-mounted bunker was designed. The self-bearing system of wall-mounted bunker that was composed by I-beam joists, steel joist bracket of bunker body with fixed anchors and self-locking bearing anchors, bearing the full weight of coal bunker on the surrounding rock and dislodging the bearing structure at the bottom of coal feeding chamber. While using electroslag pressure welding, high-strength impact resistant materials and other advanced technology and new materials, the overall process of bunker wall-mounted was improved, the construction time of bunker was shorten, and the cost of construction and maintenance for coal feeding chamber also was reduced. Field test proved the reliability, obviously technical and economical benefits.
