〔本刊讯〕F-DS(凡口大直径深孔)采矿法是由凡口铅锌矿、北京矿冶研究总院、长沙矿山研究院共同承担对VCR采矿法试验研究的成果。凡口铅锌矿是我国主要铅锌生产基地,多年来采用水平分层充填和浅眼留矿法回采矿体。由于效率低、作业不安全,一直未能达产。为了使凡口铅锌矿尽快达到设计产量,1981年12月国家有色金属管理总局下达凡口铅锌矿F-DS采矿法试验研究任务,并与国家科委、中国有色金属工业总公司签定
[News] F-DS (where the mouth of large diameter deep hole) Mining Law is the lead-zinc mine by the mouth, Beijing Mining and Metallurgical Research Institute, Changsha Institute of Mining jointly bear the VCR mining research results. Fankou lead-zinc mine is the main lead-zinc production base in China. For many years, it has adopted horizontal stratified filling and shallow-hole retention mining method to recover ore bodies. Due to low efficiency, unsafe work, has failed to reach production. In order to achieve the designed output of Fankou lead-zinc mine as soon as possible, in December 1981, the State Non-ferrous Metals Administration issued the F-DS mining test of Fankou lead-zinc mine and signed the contract with the State Science and Technology Commission and China Nonferrous Metals Industry Corporation
