To address the frequent occurrence of roof caving,severe over-excavation,and significant ore loss in a mine stope,combined with the limited operating space due to extremely thin ore veins,a bolt + double reinforcing bar support technology is proposed.The essence lies in the timeliness and flexibility of double reinforcing bar support,which allows the entire row of bolt groups to act collectively under the action of the support board during the support process,thereby stabilizing critical rock blocks that may cave in.This support scheme effectively solves the problem of supporting extremely thin ore veins,improves stope safety,and reduces ore dilution,thus enhancing the economic benefits of the mine.
