近三年来，在国家大抓黄金生产，特别是85年4月国务院发出“‘七五’期间黄金生产要有较大幅度增长”的指示后，全国黄金生产队伍增加到三万多人，在“岩金和砂金并举”的精神指导下，砂金矿勘探工作有了进一步发展，并已建立起一支具有一定规模的砂矿钻探技术队伍。据不完全统计，1985年全国冶金、有色、地矿、建材系统开动砂金钻机近200台，年完成工作量约14万米，为国家提供了一批很有价值的急需的砂矿床；1986年全国开动砂金钻机364台，计划工作量22万余米，砂金钻探达到了历史上空前发展的水平。
In the past three years, with the state’s grasping the gold production, especially since the State Council issued the directive in April 1985 that “the gold production should have a substantial increase during the Seventh Five-Year Plan”, the national gold production team has increased to more than 30,000. Under the guidance of the spirit of “both gold and gold deposits”, the gold and gold exploration work has been further developed and a certain number of sand mine drilling technical teams have been set up. According to incomplete statistics, nearly 200 sand and gold drilling rigs were started in 1985 in the metallurgy, nonferrous metals, minerals and building materials systems in the country. The annual workload of about 140,000 meters was completed, providing a batch of very valuable and valuable sand deposits to the country. In 1986 There are 364 placer drilling rigs operating nationwide, with a planned workload of more than 220,000 meters. Sand drilling has reached an unprecedented level of development in history.
