| 摘 要： | 对安庆铜矿特大型采场不同灰砂配比的充填体进行了无侧限单轴抗压试验，根据试验测得的单轴压缩韧度参数，了解了胶结充填体的韧性性能。分析了充填体韧性指数性质的变化及其规律，认为矿山保证充填体完整性最现实的要求是使充填体具有较高的残余强度。这一结论对矿山提高充填体质量具有一定的指导意义。

| Abstract: | In this paper, the unconfined uniaxial compression tests on backfills with different cement - tailings ratio in the special large -sized stope in Anqing copper mine are presented. According to the obtained uniaxial compression toughness parameters, the toughness properties are known. The variety of the properties of toughness indexes and the laws are analyzed. It is argued that the most realistic requirement for keeping the integrity of backfill is to assure the backfill with high residual intensity. |
