Cemented paste backfill (CPB) is used as a support and filler material in underground mines. In underground conditions, before mine closure and flooding, surface and groundwaters with variable quality are in contact with CPB material, which may result in the leaching of harmful substances from the CPB. In this study, we used actual mine water from a gold mine to flush CPB in a laboratory test to simulate underground conditions and the environmental influence of CPB on groundwaters more realistically than before.

柱实验期间胶结膏体回填 (CPB) 和周围中性矿井水的相互作用

水泥浆回填（CPB）用作地下矿山的支撑和填充材料。在地下条件下，在矿井关闭和洪水之前，不同质量的地表水和地下水与 CPB 材料接触，这可能导致有害物质从 CPB 中浸出。在这项研究中，我们在实验室测试中使用金矿的实际矿井水冲洗 CPB，比以前更真实地模拟地下条件以及 CPB 对地下水的环境影响。
