中国有色金属工业总公司委托广州公司于1983年11月17～19日,在广东石人嶂钨矿,召开了振动放矿留矿法开采钨矿脉的技术鉴定会。广东省采矿科技情报网同时召开了技术推广会。来自全国工、矿与院所的代表共62人。在我国钨矿开采中,采用浅孔留矿法占相当大的比重,由于重力自溜放矿工艺存在很多的缺点,长期以来,钨矿开采技术一直较为落后。为了改善和提高钨矿开采的技术经济效果,1981年中南矿冶学院与广东石人嶂钨矿合作,进行了振动放矿留矿法开采钨矿脉的试验研究。经过两年来的努力,完成了试验室模拟试验,并在该矿石人嶂坑口的2240、
China Nonferrous Metals Industry Corporation commissioned the Guangzhou company in November 17, 1983 to 19, in Shirenguan tungsten, Guangdong, held a vibration ore dressing mining tungsten ore veil technology appraisal meeting. Guangdong Provincial Mining Technology Information Network held a technology promotion meeting at the same time. A total of 62 representatives from workers, mines and institutes across the country. In the exploitation of tungsten ore in our country, the shallow hole retention method accounts for a large proportion. Due to the shortcomings of the gravitational self-slip discharge process, the tungsten mining technology has been relatively backward for a long time. In order to improve and enhance the technical and economic effects of tungsten mining, Zhongnan Mining and Metallurgy Institute cooperated with Guangdong Shirenguang Tungsten Mine in 1981 to carry out the experimental research on the recovery of tungsten ore veins by vibrational ore leaching. After two years of hard work, completed the laboratory simulation test, and in the ores of the ore 嶂 pit mouth 2240,
