摘要
针对某金矿矿床的赋存状况,开采人员结合矿井现有技术力量、开采设备和设备状况,采取了无底柱浅孔留矿开采方法,以解决矿体贫化和流失问题,并获得了一定的经济效果。无底柱浅孔留矿法通过实际应用证明是一种有效的开采方法,完全符合本矿的实际情况。该方法是当前用于回采极薄倾斜矿体的一种常用开采方法,并详细分析了其优势、特点、工艺过程和适用条件。结合某金矿实例,总结了该方法在实践中的应用,并对其经济和技术指标进行了概括,具有一定的参考价值。无底柱浅孔留矿法是国内金矿山常用的一种开采方式。研究者提出在中小型矿山开采急倾斜薄矿脉时,可以采用无底柱底结构以减少矿体损失,并提高矿井的安全性和综合效益。
In response to the occurrence status of a certain gold deposit,the mining personnel combined the existing technical strength,mining equipment,and equipment conditions of the mine to adopt a shallow hole shrinkage mining method without bottom pillars,which solved the problems of ore dilution and loss,and achieved certain economic results.The non pillar shallow hole shrinkage method has been applied in practice and is an effective method,which is in line with the actual situation of this mine.The non pillar shallow hole shrinkage mining method is currently a mining method for mining extremely thin and inclined ore bodies.Its advantages,characteristics,technological process,and applicable conditions were comprehensively analyzed,and its application in practice was summarized based on a certain gold mine example.Its economic and technical indicators were summarized,which has certain reference value for its application.
