通过测试尾砂的物化性质，开展沉缩试验、沉降试验、渗透试验全面掌握了金山矿业公司尾砂的基本特性；对不同龄期、不同灰砂比及不同浓度尾砂充填体进行的强度试验，了解了金山矿业公司尾砂胶结充填体的强度性能，且进一步分析了尾砂充填体强度的影响因素，从而为井下充填采矿提供了基础技术数据支持。
The physical and chemical properties of the backfilling tailings are tested .The basic characteristics of the tailings in Jinshan are obtained by shrinkage ,settlement and penetration tests .To get the strength properties of the tailings cemented filling bodies , the strength test is also proceeded against different periods , cement-sand ratios and concentration .The influence factors to the strength of the tailings cemented filling bodies are further analyzed , which provide basic data support for the underground backfilling mining .
