摘要
诸暨璜山金矿改留矿法、小中段空场法为下向分层进路回采胶结充填采矿法,使矿山一年多盈利90万元(按年产1.5万吨矿石计)。本文介绍该采矿法的回采方法与碎石混凝土充填工艺,并对其技术经济指标作简要分析。
Underhand cut-and-cemented fill stoping method is used to rplace ori-ginal shrinkage method and sublevel stoping method in Huangshan Gold Mine, Zhuji. As a result, the mine has achieved net profit of 900,000 yuan(estimated production 15,000 mtpy) just over a year. In the paper, the mining technology of cemented fill stoping and backfill technology with rubble and concrete are presented, and their technical and economical indexes are briefly analyzed.
