摘要
东边坡矿区是厂坝铅锌矿露天开采时留下的露天边坡,在实际的开采中出现了出矿品位降低的问题。本文通过对东边坡矿区开采现状的调查,试图分析造成品位降低的原因,并总结出一套经济合理、切实可行的提高出矿品位的技术方案。
Dongbianpo Mining area is the slope residue of open-pit mining left by the Changba lead zinc mine before ,and in the actual mining there existed the problem of grade drop of ore mined out .By investigation of exploitation status in eastern slope mining area ’ , attempt was made to analyze the reason of grade drop , and summarize a set of technical solution that can improve the ore mined out economically , reasonably and practicably .
