干式充填采矿法若干技术进步

Several technical developments of dry-type filling-mining technique

岩金作为贵金属矿床 ,提倡使用损失率、贫化率低的充填采矿法开采。文中介绍了近年来干式充填采矿法的试验研究、应用情况 ,以及若干技术进步 ;以浅孔留矿采矿法为主的空场采矿法而应用干式充填采矿法主要是形成人工间柱 ,使相邻采场能应用空场采矿法回采并起到支撑空区的目的 ,这样的干式充填采矿法有许多独特之处 ,本文略作介绍。

Filling-mining technique should be accepted to mine lode gold because of its advantages of low depletion rate and lost rate. The paper introduced the experimental research,application and several technical developments of dry-type filling-mining technique. Dry-type filling-mining technique used in openstope method which usually uses hallow shrinkage stoping is mainly to for m artificial spatial ore column,therefore supporting themined areas and being helpful formining the adjacent stope.
