小煤柱沿空支护技术

Support Technology for Roadway Driving along Goaf with Minor Pillars

本文针对在小煤柱沿空送巷掘进施工中,采用锚杆、锚索、高强度钢筋网、喷碹联合支护技术。减少了煤柱损失,有效地控制了巷道的变形量,提高了施工的安全性。

During the construction of roadway driving along goaf with minor pillars,combined support with anchor bolts,anchor cable,reinforcing mesh,enforcing mesh and shotcreting are used to cut pillar losses,and control the deformity of the roadway,so as to enhance the safety of construction.
