Analysis of Long-term Strength of Full Tailings Cemented Filling Body in Wushan Copper Mine
摘要
Abstract
A full tailing cemented filling body made of full tailings in Wushan Copper Mine and cement is taken as the research object, the long-term strength test of the tailing cement filling body was carried out by the uniaxial compression method using the RMT-150C hydraulic servo control system, the relationship between the long-term strength of filling body and cement-sand ratio and the mass concentration of slurry was studied. The test results show that: with other factors unchanged, with the increase of slurry mass concentration or cement-sand ratio, the strength of the filling body gradually increases, and the increase of the strength of the filling body also increases. The cement-sand ratio and the concentration of slurry affected both the long-term strength of the filling, and the effect of cement-sand ratio on the long-term strength of the filling was greater than that of the slurry.关键词
