摘要 对充填体的强度控制型和剪切控制型破坏形式模型进行了力学分析,建立了两种破坏模型的极限状态方程,对影响充填体可靠度指标的因素进行敏感性分析后发现,强度控制型破坏模型中充填体自身的单轴抗压强度对可靠度指标影响较大,剪切控制型破坏模型中充填体的粘聚力对可靠度指标影响较大。以三山岛金矿深部采场为例进行了可靠度分析,经过计算发现采用配比1∶8的充填体可达到安全回采的要求,对现场实际生产有指导意义。 Two limit state equations were established based on mechanical studies on the compression-dominant and shear-dominant failure modes of backfilling body.Sensitivity analyses of the factors affecting the reliability index of backfilling bodies indicated that the uniaxial compression strength of backfill in the compression-dominant failure model and cohesive force in shear-dominant failure model had a bigger influence on the reliability index.Taking the deep mining practice in Sanshandao Gold Mine as an example,reliability calculation showed that backfilling body with the proportion of 1∶8 could meet the requirement of safe stoping.The result provides guidance to the on-site production.
