| 摘 要： | 凡口铅锌矿深部矿床的开采，是凡口矿持续稳产发展的重要保证。在分析深部矿床赋存特点及深部开拓方案的基础上，提出了2种开采顺序方案，并运用三维弹塑性有限元方法对2种开采方案进行了数值模拟分析，结果表明采用由下至上的开采方案能实现深部矿体安全高效、经济合理的开采。该方案己应用于生产实践中。

| Abstract: | The mining of deep deposit is an important guarantee for the sustainable and stable development of Fankou Lead- zinc Mine. Based on the analysis of the characteristics of deep deposit occurence and the deep devlopment scheme, two alternatives of mining sequence were proposed and numerical simulation analysis was made of the alternatives by 3D elastoplastic FEM. The results indicated that the upward mining scheme could realize a safe, high-efficiency and economically reasonable mining of deep orebody. The sheme has now been applied in production. |
