一、引言 1978年,枥洞矿由于有色金属需求不振、价格暴跌、日元外汇比价空前之高等原因,收支出现很大逆差,因此不得不采取以下等各项措施: (1)原矿产量从4800吨/日减到3200吨/日; (2)人员合理化(削减295人,由560人减到265人); (3)削减开采成本高的矿体的采矿量,转为增加开采成本低的优质矿体的采矿量。 1979年,由于上述合理化措施见到成效以及有色金属价格的回升,收支已经恢复顺 I. INTRODUCTION In 1978, due to sluggish demand for non-ferrous metals, plummeting prices and the unusually high foreign exchange parity rate in the yen, a huge deficit in revenue and expenditure occurred in Stable Cave Mine. Therefore, the following measures have to be taken: (1) 4800 tons per day to 3200 tons per day; (2) rationalization of personnel (reduction of 295 from 560 to 265); (3) reduction of the mining volume of ore bodies with high mining costs and the reduction of mining costs The amount of high-quality ore body mining. In 1979, due to the above rationalization measures and the recovery of non-ferrous metal prices, the revenue and expenditure have been resumed
