机械化上向进路充填采矿法在山东焦家金矿试验成功,并已在该矿推广应用。这项科研成果是由长沙矿山研究院与焦家金矿共同研究成功的。日前,国家黄金管理局组织北京科技大学、东北工学院、北京矿冶研究总院、北京有色冶金设计研究总院等十几个单位的专家进行了鉴定。专家们认为,该成果为我国蚀变岩型金矿破碎难采矿休的开采提供了一种安全、经济、高效的采矿方法。该方法采用水平进路回采,使用柴油驱动、液压凿岩的多功能小型台车打眼,非电导爆管起爆,采场控制爆
Mechanization of the road filling mining method in Shandong Jiaojia gold mine test success, and has been in the mine to promote the use of. This research result is successfully researched by Changsha Mining Research Institute and Jiaojia Gold Mine. Recently, the State Administration of Gold Organization Beijing University of Science and Technology, Northeast Institute of Technology, Beijing Mining and Metallurgical Research Institute, Beijing Nonferrous Metallurgy Design Research Institute more than a dozen units of experts were identified. Experts believe that the results provide a safe, economical and efficient mining method for the mining of fractured refractory gold deposits in China. The method adopts horizontal approach to mining, diesel-driven, hydraulic rock drilling multi-functional small car drilling, non-conductive burst tube explosion, stope control burst
