粗骨料胶结充填材料性能研究

为减少尾砂排放带来的污染及运作成本，在确保充填体强度、安全开采的前提下，将尾砂掺入戈壁集料用于井下充填是一种行之有效的方法，为此进行了一系列相关的试验研究。通过配合比试验得到所需的技术参数，并从粗、细骨料分布特性详细地分析了不同配合比试块强度产生差异的内在原因，对其形成的承力架构及破损特征进行了描述，为从根本了解粗骨料混凝土充填材料力学性质的成因及对其进行控制调节提供依据。

Study on the Material Performance of Coarse Aggregate Cemented Backfill

For decrease the contamination and disposal cost of tailings and made tailings as a kind of filling material could settle this difficult problem. After a series of mixture ratio tests got needful technique parameter, then analyzed distribution characteristic of coarse ＆ minute aggregate granule and analyzed intrinsic causation what eouse strength＇ s difference of different mixture ratio, described beating structure and disrepair character,which could provide reference to mines work of filling and analyses the mechanics properities of coarse aggregate backfill.
