摘　　要：在新疆喀拉通克铜镍矿实施了开采环境再造深孔诱导崩矿充填法的现场工业试验。人工顶板第二分层构筑过程中,首采进路回采完后,对其预埋应变计和测缝计,然后进行充填。其它进路进行回采充填时,对首采进路充填体内的应力和位移进行监测。监测结果表明:首采进路充填体内的应力由压应力向拉应力逐步转变,位移随着时间的变化出现增大的现象,最大为22.4mm;进路回采完成后,若不及时进行充填,将影响到本身进路的构筑效果,使周围进路内产生剪切应力。The field industrial test was performed in Kelatongke Copper-nickel Mine in Xinjiang,on environment reconstruction for mining by the induced blasthole stoping with backfill.In the process of building the second layer of artificial roof,strain gauges and joint meter were embedded after stoping work of the initial drifts completed and then filled.The stress and displacement of backfill in the initial mining drifts were monitored when mining and filling were progressing in other drifts.Results show that the compressive stress status of backfilling gradually transformed into tensile stress status,the displacement increases with the change in time,being up to 22.4 mm maximally.If backfilling can＇t be carried out promptly after the drift stoping work finished,it will affect its building results,inducing the shear stresses of surrounding drifts.
