国家重点黄金科技攻关项目——倾斜破碎矿体抛掷充填采矿法,已在焦家金矿研究成功,并通过了国家黄金管理局组织的鉴定。 焦家金矿是我国的重点黄金企业,蚀变岩型倾斜破碎矿体占总矿量的40％左右。这种矿体倾斜度大,节理发育岩石破碎,用一般方法采矿,矿床易大面积塌方,危险性大。由焦家金矿与长沙矿山研究院共同承担“倾斜破碎矿体抛掷充填采矿法”的研究课题,解决了破碎矿体开采的技术难题。 该充填采矿法,是采用非电微差控制爆破技术落矿,电动铲运机出矿,锚杆、锚
National key gold science and technology research project - Tilting broken ore body throwing and filling mining method, has been successfully studied in Jiaojia Gold Mine and passed the appraisal organized by the State Administration of Gold. Jiaojia Gold Mine is a key gold enterprise in China. Alteration rock-tilt inclined ore bodies account for about 40% of the total ore amount. This ore body inclination, joint development rock broken, using the general method of mining, easy to large-scale deposit collapse, dangerous. Jiaojia Gold Mine and Changsha Institute of Mining jointly undertake the research project of “Tilting broken ore body throwing and filling mining method”, which solves the technical problems in the mining of broken ore bodies. The filling mining method is the use of non-micro-controlled blasting demolition technology, electric scraper ore, anchor, anchor
