摘要
本文结合黑河地区采金船开采砂金矿的实践和各种砂金矿开采方法的特点,分析探讨了适合永久冻结砂金矿的开采方法.并指出推土机和铲运机(包括它们与其它采掘机械联合的开采工艺)较适合永久冻结砂金矿的开采.文中还着重介绍了融化层合理厚度和所必须采场面积的确定原则和方法.
This paper discusses some methodls suitable for the placer gold mining in permafrost area on the basis of the pratice of the gold dredger mining in Heihe Area and the characteristics of various methods of placer gold mining. We also point out why bulldozer-scraper is fit for placer gold mining in permafrost area.The principle and methods to determine the reasonable thickness of melting layer and stope area are introduced here emphatically.
