摘要
分析了新型网壳锚喷支护结构中各部分的作用、支护条件下弹塑性和网壳锚喷支护结构在实际矿区监测数据,该新型网壳锚喷支护结构施工较为简单,既可以承受较大围岩压力,又能够使用较少材料使混凝土层让压,对于软岩高应力巷道支护具有推广意义。
Analyzed the role of each part of the new net shell bolt and shotcrete support srtucture, dastic-plastic under the condition of supporting and the monitoring data of net shell bolt and shotcrete strcucture in actual field. The new net shell bolt and shotcrete support structureis simple for construction of, not only can withstand larger pressure of surrounding rock, and be able to use less material to make the concrete layer pressure, for high stress soft rock roadway is more widely available.
