江西十二个钨矿用留矿法开采的矿量约占整个矿石开采量的80％左右。采用留矿法回采的方案,大约有几十种之多。其中,有些方案至今还在使用,有些方案由于各种原因及变化因素,早已被淘汰或已不再使用。对这样种类繁多的留矿法回采方案,如何来进行科学的分类,无疑对进一步总结、提高留矿法以及在新的开采技术条件下扩大留矿法的使用范围,都将是一件有意义的工作。
Twelve tungsten mines in Jiangxi Province have been mined with mineral deposits that account for about 80% of the total ore production. There are dozens or so of programs that adopt the mineral recovery method. Some of these programs are still in use so far. Some of them have long been eliminated or no longer used due to various reasons and factors. How to categorize such a large number of mining-retained recovery schemes will undoubtedly be of great significance to further summarizing and improving the retention method and expanding the scope of application of the mining-retention law under the new mining technology conditions work.
