| 英文摘要 | The stability of tailing dam has an important influence on the surrounding ecological environment and the security and property of people. This article, from the micro perspective, analyzes of the water-tailing chemical interactions and process and analyzes its effects on tailing micro structure and dam stability. The experimental results show that ferrous iron in water(PH=9.5-10.3) is constantly in contact with the air and then produces a series of reactions such as oxidation, eventually becomes a clogging substance what mainly include Fe(OH)(3), the chemical clogging substances mainly include Fe(OH)(3), some cements and strong adsorption humus groups that will block the pore channels and absorb the ions or tailings in water to form a larger group that accumulating in porous media and drain mouths will result in poor seepage and affect its permeability; The chemical clogging can reduce the stability of tailing dam. Those researches of chemical process of tailing dam will provide directions references for tailing dam security-research and the improvement of tailing dam water-environment. |
