某铀矿应用横撑支柱留矿法的探讨

Feasibility study of application of stulled shrinkage stoping in a uranium mine

某铀矿对于围岩不稳固、急倾斜薄矿体主要采用浅孔留矿法进行回采。该采矿法回采安全性差,贫化率高,经济效果差。若采用横撑支柱留矿法回采,将会有效地解决上述问题。

Due to its own production limitation, normal shallow hole shrinkage stoping was used to mine steep thin ore bodies with unstable surrounding rock in a uranium mine. The method brought about low mining safety eoeffcient,high dilution rate and poor economic effect during mining. The feasibility of adopting the stulled shrinkage stoping to mine the ore bodies are studied, and the stulled shrinkage stoping is compared with the shallow hole shrinkage stoping. It is considered that the above problems can be solved by using the stulled shrinkage stoping.
