1972年9月瑞典阿特拉斯公司(AtlasCopco)在斯德哥尔摩市主持召开一个有欧洲、北美、南美和澳大利亚的部分国家参加的“无底柱分段崩落法讨论会”。会上宣读了有关技术和经济等方面的论文共九篇。遵照伟大领袖毛主席关于“洋为中用”的教导,我们组织北京矿冶研究院和北京钢铁学院的有关同志选译了以下六篇:1.“克雷格芒特矿无底柱分段崩落法的一些实际问题”(加拿大),涂继正译;2.“无底柱分段崩落法中重力流动过程的研究”(瑞典),刘之祥、苏宏志译,童光煦校;3.“豌豆岭矿的无底柱分段崩落法”(美国),贯洪林译,涂继正校;4.“无底柱分段崩落法的产量”(瑞典),朱烨译,涂继正校;5.“一个现代化无底柱分段崩落法矿山的概况”(瑞典),涂继正译;6.“无底柱分段崩落珐技术的最优化和应用”(加拿大),宗海祥译;为了适应我国矿山研究和推广无底柱分段崩落法的需要,本刊将连续刊载上述译文,供有关读者参阅。
September 1972 Atlas Copco of Sweden presided over a “pillarless subsidence caving seminar” in Stockholm with participation of some countries in Europe, North America, South America and Australia. At the meeting read a total of nine papers on the technical and economic aspects. Following the guidance of Chairman Mao of the Great Leader on “Foreign Matter”, the relevant comrades of Beijing Institute of Mining and Metallurgy and Beijing Institute of Iron and Steel were selected to compile the following six articles: 1. “ Some Practical Problems of Column Caving Method ”(Canada), Tu Jizheng; 2. Research on Gravimetric Flow Process in Slitless Caving Method (Sweden), Liu Zhixiang, Su Hongzhi, Tong Guangxu, 3. “Pedestal Column Caving Method for Pea Ridge Mine” (USA), translated by Guan Honglin, Tu Jizheng School; 4. “Output of Sillless Caving Method” (Sweden), translated by Zhu Ye , Tu Jizheng school; 5. “a modern subsea caving method of mining” (Sweden), Tuo Ji is translated; 6. “the optimization and application of pillarless caving technology ” (Canada ), Zong Haixiang translation; In order to meet the needs of mine research and promotion of non-pillar sub-caving method, this publication will be continuously published the above translation for the reference of the readers.
