长锚索预加固采场顶板,是抑制开挖工程岩体变形和对失稳岩体进行预加固的有效措施之一。以河西金矿上向水平分层尾砂胶结充填采矿法为工程背景,介绍了钢丝绳(钢绞线)长锚索结构和支护参数,叙述了充填采场长锚索预加固施工工艺过程。充填采场实施长锚索预加固措施后,收到了良好的护顶效果。
he use of long cable to pre-reinforce stope roof is one of the effective measures to keep the excavation engineering rock mass from deformation and instability .The paper takes upward sublevel slicing filling method used in Hexi gold mine for engineering background ,introduces the structure and supporting parameters of steel wire rope long cables and describes the pre-reinforcement process using long cables .After the pre-reinforcement ,the supporting effect is enhanced .
