由赣洲有色冶金研究所、大吉山钨矿、南昌有色冶金设计研究院共同研究成功的“爬罐浅孔留矿法,”七月六日在长沙通过鉴定。会议由中国有色金属工业总公司主持,来自全国各地的四十多位总工程师高级工程师及其他学者,经过七天的评议认为;爬罐浅孔留矿法是我国薄矿脉开采技术中一项重大突破。与普通留矿法比较,采矿强度由14吨/米~2、月提高到51.38吨/米~2、月;工班效率由7～8吨/工班提高到14.8吨/工班;天井掘进速度由10.3米月/提高到53.8米/月;坑 By the Ganzhou Institute of Nonferrous Metallurgy, Daye Mountain tungsten, Nanchang Institute of Nonferrous Metallurgy Design and Research Institute of the successful study of “climbing tank shallow hole retention method,” July 6 in Changsha through the identification. The meeting was chaired by China Nonferrous Metals Industry Corporation. More than 40 chief engineer senior engineers and other scholars from all over the country said after a seven-day evaluation that the shallow-hole retaining method of climbing cans was a major breakthrough in the exploitation of thin-veined ore in China . Compared with the ordinary ore retention method, the mining intensity increased from 14 t / m ~ 2 to 51.38 t / m ~ 2 in January and the work efficiency improved from 7 ~ 8 t / work to 14.8 t / work; Speed ​​from 10.3 m / up to 53.8 m / m; pit
