苏联杰兹干矿井下巷道掘进中,试验了两种支护方式—钢聚合物锚杆和乳胶喷射混凝土。钢聚合物锚杆使用了聚乙烯瓶装的固结剂。其主要成分为含速凝剂和填料的聚脂树脂以及固化剂。安设2米长的锚杆,需装 6瓶固结剂(锚杆孔径为42毫米)。安装时用CBY—2M型自行设备将长1.6米、直径18毫米的变截面钢筋插入孔中,边插入边回转破坏瓶子外壳,使其中成分均匀。该锚杆安装后一小时,锚固强度为85～92千牛顿,最终为105～110千牛顿。为防止岩石风化,进
Two types of support methods were tested in the Soviet Jetzi mine tunneling - steel polymer anchor rods and latex shotcrete. Steel polymer anchor using a polyethylene bottle of the consolidation agent. Its main components are quick-setting and filling polyester resin and curing agent. Install a 2-meter anchor and a 6-neck anchor (bolt diameter 42 mm). Installation with CBY-2M-type self-equipment will be 1.6 meters long, 18 mm diameter cross-section of steel inserted into the hole, insert the side edge of the rotary damage to the bottle shell, which made the ingredients evenly. One hour after the anchor was installed, the anchoring strength was 85-92 kilo-newtons, eventually 105-110 kilonewtons. To prevent rock weathering, into
