| 摘 要： | 为检测水泥-尾砂充填体内部构造和力学性能,采用钻芯法从采场充填挡墙或相应部位施工覆盖整个采场的地质孔取样,使用SY-1型声波仪对样品进行声波测试,通过配套软件分析波形和频谱.结果表明:波速和动弹性力学指标的差距源自强度和疏密构造差异;虽不同充填体声波波速不同,但其声波波形和频谱成分基本相同;声波延时长、主频集中、频谱较简洁且振幅较高,反映出充填体内部夹杂、孔洞和空穴等缺陷少,结构较完整.

| Abstract: | For detecting the interior conformation and mechanics capability of cement-tailing backfill,the sampling method of bore drilling was adopted from filling blocking walls or other corresponding parts which could cover all the stope to get backfill cores. The acoustic wave velocity of the samples was tested by use of SY-1 type acoustic testing apparatus,and then the spectra and waveforms were analyzed by way of correlative software. Testing results indicate the difference between acoustic wave velocity and ela... |
