摘　　要：南京铅锌银矿地下开采遗留的大量采空区已严重威胁了风景区的地表稳定，区内不断发生地表沉降、塌陷等地质灾害。在本项目研究中，提出用全尾砂加高水固化材料进行采空区处理的方案，并进行了工业试验，效果良好，且经济效益明显。实践证明，该方案是适合南京铅锌银矿特殊地理位置条件下一种有效的空区处理手段。A great large of mined out area formulated by underground mining at Nanjing Lead zinc silver Mine has influenced the stability of land scene area. Geotechnical hazard such as land subsidence and collapse brought out continually. A processing method by using full sand end mixed with high water consolidated material is discussed and experiment is proceeded. In the project, it proved to be effective and economical. The mitigation method is proved to be suited for Nanjing Lead zinc silver Mine in a special location.
