三年来,各矿在采探技术的发展上有着显著的不平衡现象,绝大部分的矿山在探矿方面不论是技术方法或作业效率上,都有了长足的进步;但是下可否认的,采矿技术与效率的发展是比较迟缓的。到目前为止,许多矿山仍旧保留了落后的劳动组织,墨守着一定的采矿方法,至于因为单纯任务观点所造成的乱采乱打现象,也是长时期没有扭转过来,因而减低了矿石的回采率。事实证明:如果这些问题得不到具体的解决,不但不可能进一步提高效率,而且也谈不到采矿作业的正规化问题。第一铜矿领导上重视了这个问题,认真贯澈了工业部一九五二年度对有色金属矿山要求的基本精神,大力支持先进工人与技术人员的合理化建议,因而取得了成绩,兹将该矿的经验介绍于本刊,希望各矿进行研究与推广。
In the past three years, each mine has a significant imbalance in the development of mining exploration technology. Most of the mines have made great strides in prospecting in terms of technical methods and operational efficiency. However, it is undeniable that mining The development of technology and efficiency is relatively slow. So far, many mines have retained their backward labor organizations and kept a certain amount of mining methods. As a result of indiscriminate chaos caused by simple tasks, they have not reversed in a long time, thus reducing the rate of ore recovery. Facts have proved that if these problems can not be solved concretely, not only will it not be possible to further improve their efficiency, nor will they be able to formalize their mining operations. The leaders of No. 1 copper mine have attached importance to this issue and conscientiously passed the basic requirements of the Ministry of Industry for non-ferrous metal mines in 1952 and strongly supported the rationalization of advanced workers and technicians. As a result, Mine experience introduced in this publication, I hope all the mines for research and promotion.
