过去由于对稀有金属砂矿的特点认识不够,在普查勘探工作中曾出現过机械套用一般矿床工作方法和管理制度的偏向,走过一些弯路。通过近几年来的实践,在各队已积累了一定經驗。为了总結經驗,提高认识,前些时候曾邀請有关单位在三一一队进行了座談。通过討論大家进一步明确了今后在稀有金属砂矿普查勘探工作中針对这种矿床的 In the past, due to the lack of understanding of the characteristics of rare metal placers, there have been deviations in the methods and management systems of general deposits used in the general survey and exploration work, and some detours have been encountered. Through the practice in recent years, certain experience has been accumulated in each team. In order to sum up experience and raise awareness, some time ago, the relevant units were invited to hold a discussion in the three-one team. Through discussion, we further clarified the future of this deposit in the exploration work of rare metal sand deposits.
