瑞典的地下采矿工业由于注重研究、注重改革而长期居于世界前列,现已进入液压凿岩、无轨开采、集中采矿、自动遥控和先进的科学管理的新阶段。1984年4月初至6月中旬,我在瑞典参观学习了3个月,考察了5个地下矿山,包括黑色、有色,大、中、小型和采用充填、崩落、空场等采矿法等各种类型。这5个地下矿山的人年平均劳动生产率为6950t(表1),比我国的大型露天矿人年劳动生产率3483t(1983年重点企业平均)还要高出1倍多。
The underground mining industry in Sweden has long been the world leader in focus on research and reform, and has now entered a new phase of hydraulic rock drilling, trackless mining, centralized mining, automatic remote control and advanced scientific management. From the beginning of April to the middle of June 1984, I studied in Sweden for three months and inspected five underground mines, including black, colored, large, medium and small, and various mining methods such as filling, caving, Types of. The average annual labor productivity of the five underground mines is 6950t (Table 1), which is more than double the annual labor productivity of 3483t (1983 key enterprises) in China.
