澳大利亚Dupont矿用产品公司生产了若干种岩层支护产品,其中有三种锚杆已转产品。①快速插入机械锚固木锚杆。快速插入机械锚固木锚杆简称RL—MA锚杆。该锚杆的特点是锚杆本身有自动锚固装置,因此安装锚杆时,勿需采用树脂锚固剂药卷;安装速度快,约10秒钟就可把锚杆插到锚杆孔里;锚杆可以让压,可切割,不会裂开;不腐蚀,因此不要求特殊的贮存条件;重量轻,易于搬运和安装。RL—MA木锚杆特别适用于巷道两帮的支护,即使巷道两帮的移动量达200mm,该锚杆也不会失效。②TP锚杆。TP锚杆是纤维加固塑料锚杆,其特点是抗剪切性能效果很好,适用于有高剪切应力岩层的支护。③ARLA木锚杆。该锚杆是一种集成式单根锚杆。该锚杆适用于高剪切应力岩层的支护。
Dupont Mining Products of Australia produces several rock support products, of which three have been converted. ① Quickly insert mechanical anchor wood bolt. Quickly insert the mechanical anchor wood bolt referred to RL-MA bolt. The characteristics of the bolt is the bolt itself has automatic anchoring device, so install the bolt, do not need to use resin anchoring agent drug roll; installation speed, about 10 seconds can be inserted into the anchor bolt hole; Anchor Rods allow pressure to be cut without cracking; non-corrosive and therefore require no special storage conditions; Light weight, easy to handle and install. RL-MA wood bolt is particularly suitable for the support of two roadway, even if the roadway two to move 200mm, the bolt will not fail. ② TP anchor. TP anchor is fiber reinforced plastic anchor, which is characterized by good shear resistance effect, suitable for high shear stress rock layer support. ③ ARLA wood bolt. The anchor is an integrated single anchor. The anchor is suitable for supporting high shear stress rock formations.
