摘　　要：针对新疆喀拉通克铜镍矿的上向水平分层充填采矿法试验采场顶板矿石水平节理发育等开采技术条件，进行了楔管式锚杆的护项试验及对锚固效果的超声波测试。生产实践和测试结果表明，支护效果良好。Aimed at the woll-developed flat joints of ore in the roof of experimental stope for horizontal cut and fill stoping method in Kalatongke copper-nickel mine, xinjiang, tests for roof support with wedze-split tube nock bolts and ultrasonic detection were performed to determine the anchorage effects. The production practice and test results showed that the support effects were fairly good.
