摘　　要：陶一矿12905工作面回风巷沿空留巷取得成功,留巷断面约1800×2000mm,获得直接经济效益1.58×106元,与新掘进巷道相比成本降低率达到16.5%。证明以锚索为主要支护型式进行沿空留巷支护是可行的。Retained gateway along empty mining area met with success on ventilated gateway of No.12905 working face in Taoyi mine. The 1.8× 2.0 square meter section was remained. It saves $1.58×106 . Compared with building a new tunneling gateway, the whole cost was cut down 16.5%. It proved that it is feasible on supporting technology by cable bolting.
