摘要
东坪金矿采用留矿法开采贫化损失很大,为此改革采矿方法,试验上向分层块石充填法,取得了显著的经济效益。本文主要介绍了采矿方法的模糊数学优选和采用的先进而适用的回采配套工艺及有关研究手段。
Shrinkage mining in DongPing Gold Mine caused high ore loss and dilution. To solve this problem, upward cut-and-fill mining stoping with rock filling was tested, yielding remarkable economical profits. Optimization of mining method based on fuzzy mathematics and advanced practical stoping technologies as well as equipment matched for stoping are described.
