地下铀矿开采方法的数值模拟技术研究

以南方某铀矿床的开采为研究对象,对可选用的留矿法、房柱法和分段空场法进行了初步分析筛选。在初步研究的基础上,对更适用的房柱法和分段空场法进行数值模拟计算研究,优化采场结构参数。综合分析和比较二者的安全性、开采效率和经济技术指标,最终确定分段空场法是该采场的最优采矿方法。

Study on Numerical Modeling Technology for Underground Mining Method

Taking one uranium ore deposit in southern province as the studying object,the relatively suitable mining methods such as shrinkage stoping method,room-and-pillars mining method and sublevel open stoping method are preliminary analyzed and screened.Based on the preliminary research result,further research on the more suitable mining methods of room-and-pillars mining method and sublevel open stoping method by numerical modeling technology are carried out,and the stope mining parameters are optimized too.By comprehensive analysis and comparison of safety,mining efficiency and economic indicators of the two methods,the sublevel open stoping method is finally determined as the best method for this stope.
