旨在确定复合锚索支护效能的实验室试验和现场试用已在加拿大的地下矿山完成。研制并试验了几种玻璃纤维锚索的作品,其中两种现在已可用于采矿工业。这种锚索的评估工作包括在加拿大和美国的试验室试验以及在加拿大几座矿山的现场试用。其目的是研制一种在价格上有竞争力、在强度上能与16mm直径钢锚素相比的复合材料锚索。除了具有相同甚至更高承载张力而外,玻璃纤维锚索由于重量轻.还可提高安装速度。与传统的钢锚索不同,复合锚索可以安装在使用连续采掘方法和需要可切割锚杆的矿山。现已完成了锚索在加拿大使用情况的市场分析。玻璃纤维锚素是矿山岩石支护的一种有效手段。玻璃纤维锚索可成为传统钢锚索的一种有效的替代品。
Laboratory tests and field trials to determine the effectiveness of composite cable anchorage have been completed at Canadian underground mines. Several glass fiber anchor cables have been developed and tested, two of which are now available for the mining industry. This type of cable assessment includes laboratory tests in Canada and the United States and field trials at several mines in Canada. The aim is to develop a composite anchor that is competitive in price and comparable in strength to 16 mm diameter steel anchor. In addition to having the same or higher load-bearing tension, fiberglass cables are light weight. You can also increase the speed of installation. Unlike traditional steel cable anchors, composite anchors can be installed at mines that use continuous excavation methods and require cuttable anchors. Market analysis of the use of cables in Canada has now been completed. Fiberglass anchor is an effective means of mine rock support. Fiberglass anchors can be an effective alternative to traditional steel anchors.
