摘要
阐述穿F7断层采用前探支护+喷碹+锚杆+挂网+喷碹+锚索+喷碹支护方式。超前支护锚杆锚固后与顶板岩石构成一体,这样使超前锚杆形成组合梁作用,放炮后,能够阻止顶板岩石冒落。
This paper describes the support way by console support, extension steel, shotcrete, bolt wire net shotcrete, rope and shotcret used in crossing F7 Fault. Forward support bolt combined with roop rock by bolting can play a roll of combined beam, which can prevent roof rock caving immediately after explosion.
