| 摘 要： | 利用选矿尾砂进行充填法采矿是一种比较成熟的采矿工艺，关键在于如何应用它。目前，夏甸金矿使用的无底柱崩落采矿法适用于产状稳定、厚大的矿体，但不适合边角矿体及破碎矿体。为了解决边角破碎矿体开采时，矿石的损失率、贫化率高和安全性低的问题，高效安全地回采更多的矿石，充分利用有限的矿产资源并满足选厂扩建后大幅度地提高处理量的需要，夏甸金矿选定多个采场，经过反复实践，认真分析，调整参数，获取了多组有效可靠的数据，最终研究出了简单有效且实用的上向水平分层进路式尾砂充填采矿法，取得了很好的经济效益。采矿是一门实践性比较强的学科，各种采矿方法可以相辅相成、取长补短，该采矿方法可以作为其他采矿方法的一个补充，具有有很好的应用价值。

| Abstract: | Mining Method of mill-run tailing filling is a relatively mature technology.The key of the method is how to apply the technology.At present,the pillarless caving is used in Xiadian Gold which is applicable for stability and heavy orebody,but not for the corner orebody or broken orebody.In order to solve the problem of high ore loss,dilution rate and low security of the corner or broken orebody mining,to mine more ore efficiently and safely,to take advantage of limited mineral resources and meet a substantial increase in the processing plant.Xiadian Gold selected multiple stope,by practicing,analysising carefully and adjusting the parameters,obtained multiple sets of valid and reliable data,and ultimately developed a simple,effective and practical mining method of horizontal stratified entrance-filling of tailing,acquired a corking economy benefit.Mining is a subject with good practical character.Every mining method may supply each other and learn from others’s strong points to offset one’s weakness.Being a supplementation to other mining methods,the mining method is introduced in this paper with a good value of application. |
