摘要
Abstract
To test the strength of the cemented tailings fill in the Gushan mine's open pit,the mining right holder has performed two geotechnical investigations.In the second time of supplemental investigation three-tube single-action rotary corer was used for sampling while drilling,which has effectively improved the recovery of the core that is not or little disturbed compared with that collected in the first time.At the same time,the more scientific and rigorous geotechnical test methods such as unconfined compression test and triaxial compression test can give more objective physical and mechanical parameters and achieve the expected strength test index.关键词
