江西的十二个老钨矿经历了三十至六十余年的开采历史,设计服务年限有的已超过,有的达到或将要达到。除少数产量大,利用资源好,生产管理较完善的矿山,其储量仍然丰富,每年尚能为国家创造一定积累外,许多矿山深感资源不足,品位降低,成本升高,经济效益差。1982、1983年有近半数的矿山亏损。脉钨矿床开采资源的充分利 Twelve old tungsten mines in Jiangxi have experienced thirty to sixty years of mining history, and some of the design service years have exceeded or been reached or will be reached. In addition to a few large-scale production, utilization of resources, better production and management of mines, the reserves are still abundant, each year can still create some accumulation for the country, many mines lack of resources, lower quality, higher costs, poor economic efficiency. In 1982 and 1983, nearly half of mine losses. Veined tungsten ore reserves of the full exploitation of resources
