摘要
针对1201运输平巷顶板为泥化软岩,易发冒顶事故且掘进速度慢的问题,分析了运输平巷围岩破坏失稳原因,从巷道支护方案和施工工序进行优化设计。工程实践表明,采用上述技术可有效控制巷道围岩变形并实现快速掘进。
In view of the 1201 haulage roadway roof for soft rock, mud is used roof caving accident and the problem of low driving speed haulage roadway surrounding rock instability causes are analyzed, from the roadway support design and construction process is optimized. The engineering practice shows that the above techniques can effectively control the deformation of roadway surrounding rock and realize rapid tunneling.
