最近报道了瑞典矿山使用锚索支护空场法采场的对比结果。在一个铁矿山,业已发现锚索支护在大直径深孔空场法中对矿柱及上盘的稳固性起很大作用。但在另一个有色金属矿山,却发现锚索支护在空场法试验采场中所起的作用并不明显。 1985年11月在吕勒欧大学召开的大型地下矿开采国际会议期间公布了这些结果。由 A recent report on the comparison of stopes with anchor cable support for the Swedish mines has been reported. In an iron mine, it has been found that anchor support plays a large role in the stability of the pillars and the upper plate in the large-diameter deep-hole airspace method. However, in another non-ferrous metal mine, it was found that the role played by the anchor cable support in the stope of the field test was not obvious. These results were announced during an international conference on large-scale underground mining in November 1985 at the University of Luleå. by
