单轴拉伸条件下充填体的力学性能研究

Study on the Mechanical Property of Backfill under Split Tension

对安庆铜矿特大型采场不同配比的充填体进行了单轴抗拉试验,根据试验测得的单轴抗拉强度、线性阶段弹性模量、峰荷应变结果,分析了这些力学性质的变化规律,对矿山提高充填体质量具有一定的指导意义,同时也对其它工程领域有一定的借鉴作用。

The uniaxial spliting tensile strength tests of backfill,at a different ratio of fill,in the special largesized stope in Anqing copper mine were made. According to the obtained test data of uniaxial spliting tensile stength, the average elastic modulus at linear phase and strain at peak load etc. , the change of these mechanical properties and their laws are analyzed, which are of certain instructive importance to the mine for improving the quality of backfill, and to other engineering fields as well.
