试论块石胶结充填体的稳定性

ON STABILITY OF BLOCKY ROCK CEMENTED FILL

块石胶结充填是我国近年来发展起来的一项充填新技术，并在大厂矿务局铜坑矿首次应用。本文介绍了首创性地采用湿选法对块石胶结充填体进行的室内力学试验，以及配合声波法所进行的现场测试，并由此确定的块石胶结充填体力学参数和力学性能；进而用有限元法进行了稳定性分析，并以回采矿柱揭露充填体对实验和分析结果进行了验证。

The blocky rock cemented filling was a new filling technique developed in re-cent years in China,and was used first time in TongKen mine operated by Dachang MineBureau. The mechanics test of blocky rock cemented fill in the laboratory was conducted,combined with the in situ test by sound wave method, the mechanics parameters and performance of blocky rock cemented fill were determined. Furthermore , the finite elementmethod was adopted to analyze its stability, and the resuIts from the tests and analysiswere examined by the fill exposed in the ore pillar recovery.
