矿山是冶金工业的基础。在发展有色金属和钢铁工业方面,当前矿山是一个薄弱环节,其中一个突出的问题就是许多矿山建成后,不能按设计能力投产,这严重地影响了投资效果,减少了矿产原料的提供。据调查,江西省十四个有色、黑色矿山,有12个没达到设计能力,占总数85%。全国有十个大中型坑内铜矿,1983年矿石总产量仅为设计能力的50%,有十个大中型铅锌矿,1983年矿石总产量仅为设计能力的67%。没有达产的原
Mine is the foundation of the metallurgical industry. The current mine is a weak link in the development of the non-ferrous metals and steel industries. One of the outstanding problems is that many mines can not be put into production as designed after they are completed. This has seriously affected the investment result and reduced the supply of mineral raw materials. According to the survey, fourteen non-ferrous and non-ferrous mines in Jiangxi Province, 12 have not reached the design capacity, accounting for 85% of the total. There are ten large and medium-sized pit copper mines in the country. In 1983, the total output of ore was only 50% of the designed capacity, with ten large and medium-sized lead-zinc mines. In 1983, the total ore output was only 67% of the designed capacity. No production of the original
