This work presents the results of the first cone penetration testing on predominately silty gold tailings in a calibration chamber, with results interpreted within the critical state soil mechanics framework. Samples were prepared at a wide range of void ratios, prioritizing loose contractive states. The results are presented in terms of the state parameter against the normalized tip resistance and are compared to some common state parameter interpretation screening tools for comparison. The modified laboratory equipment, sample preparation methods and characterization of the tested silty tailings are described along with the adapted void ratio tracking method.

使用新的小型校准室对粉质尾矿进行锥孔渗透测试

这项工作介绍了在校准室内主要是粉质金尾矿的第一个锥体渗透测试的结果，并在临界状态土壤力学框架内解释了结果。以宽范围的空隙率制备样品，优先考虑松散的收缩状态。结果以状态参数相对于归一化的尖端电阻的形式给出，并与一些常见的状态参数解释筛选工具进行比较。描述了改进的实验室设备，样品制备方法和测试粉质尾矿的特性，以及改进的空隙率跟踪方法。
