摘要
针对金川三矿区恶劣的地质条件,施工过程中采用了湿喷钢纤维混凝土与锚杆联合支护,用湿喷工艺代替干喷工艺。湿喷混凝土强度高,粉尘少,适应变形能力强,经济上也较合理。
According to the complicated geologic condition of Jinchuan No.3 mine area, shotcrete with steel fiber and bolting were used in tunnel construction, and wet spray method replaced the dry spray method. Wet spray method has high strength, low dust, and is reasonable in economy.
