在党中央大力发展铜铝的号召下,祖国各地正在掀起着铜铝生产的热潮,土法采铜亦如雨后春笋。为了有助于交流情况,我们将某地区所属几个土法开采铜矿所了解到的一些情况,特别是采矿方法上,提出一些初步意见,仅供各土法开采矿山参考。 With the vigorous development of copper and aluminum by the Party Central Committee, the craze for copper and aluminum production is setting off in various parts of the motherland. There is also a springing up of indigenous copper mining. In order to facilitate the exchange of information, we have made some preliminary comments on some of the conditions learned by several indigenous mining copper mines in a certain area, especially the mining methods, and are only for reference by mining by each indigenous law.
