白芦煤矿巷道锚杆支护技术方案优化

Optimization of roadway bolt supporting technology in Bailu Coal Mine

锚杆支护已成为目前巷道支护的主要支护方式,它与锚索、网、喷浆等配合使用,形成了多种支护方式。通过理论和实际相结合的方法,验证了白芦煤矿锚杆支护存在着支护强度过大的问题,造成生产成本高;因此,在保证安全的前提下提出优化支护技术方案,对于安全高效生产具有重要理论意义和应用价值。

Bolt supporting has become the main supporting method of roadway supporting, which is used with anchor, mesh, shotcrete and so on, and forms a variety of support methods. Through the method of combining theory and practice,it was verified that the strength of bolting supporting in Bailu Coal Mine is too large,resulting in high production costs; therefore, optimization scheme supporting technology was put forward under the premise of ensuring safety9which has important theoretical significance and application value for the safe and efficient production.
