摘要
管缝式锚杆能较好地锚固岩石,因此在采矿业中被广泛应用。通过对用沙坝破碎矿岩采场顶板进行管缝式锚杆支护试验,证明管缝式锚杆支护相对于传统支护方式及其他类型锚杆支护有较大优势,是一种支护及时、经济有效的新型锚杆支护形式,是支护改革的一个方向。
Split rockboh has been applied widely in mining because of its excellent rock-anchorging. Based on the experiment of using split rockbolt support in roof stope of fractured ore-bodies in Yongshaba mine,the paper proves that split rockbolt support in fractured ore-bodies has advantages over the traditional support and other rockbolt supposing types.Meantime,the paper states that it is a new,timely and effective supporting form and it is a reform direction for developing support.
