摘要
根据古汉山矿西大巷地质特点,设计了新型的三格栅三拱组合成的双层双曲空间网壳支架,在喷射混凝土后形成网壳配筋衬砌结构,使喷层整体既具有一定的可缩性,又能承受强大的变形地压,在软岩巷道中进行的工业性试验取得了很好的支护效果.
Based on geologic features of the West Roadway of Guhanshan Coal Mine, late-model double-deck double-bend space net-crust bracket, which is composed of three-case-bar and three-arch, is designed. After spraying, the loading-carrying structure is formed, and the structure has good plasticity, that is, it can bear great rock pressure. Good support results have been achieved on the spot.
