摘要
结合兴安煤矿四水平中央泵房的工程实践,分析了在掘进巷道中锚网索喷支护的工程特点。工程实践表明,锚网索喷支护显著提高了围岩的强度和承载能力,有效地控制了巷道变形,是大断面岩巷施工的一种新的支护形式。
In combination with the central pump chamber construction in No.4 Level in Xing＇an Coal Mine,the engineering characteristics of combined support with bolt wire cable and shotcrete in roadways driving are analyzed.Engineering practice showed that combined support with bolt wire cable and shotcrete significantly increased the strength of rock and carrying capacity,effectively controlled the roadway deformation.It is a new support way in the construction of large section rock roadway.
