摘要(Abstract)：

为了研究矿山粗骨料(废石)充填的新模式,达到矿山绿色生产的需求。首先在大量试验的基础上给出了粗骨料料浆的高浓度特征。其次对大红山铜矿的废石与尾砂进行级配分析,选用最优配比m(废石)∶m(尾砂)为6∶4进行流变试验,分析其流变特性。最后应用双因素方差法分析了水泥添加量与质量浓度对屈服应力的影响。结果表明,废石-尾砂高浓度料浆属屈服-假塑性体,水泥添加量对屈服应力的影响更显著,屈服应力与水灰比及骨料体积分数存在定量的关系。在此基础上,建立了屈服应力的预测模型,预测结果的误差在5%以内。

关键词(KeyWords)： 环境工程学;废石-尾砂;流变特性;高浓度;屈服应力预测模型
