从二里河金矿采矿实践看金矿勘查开发应注意的问题
|
摘要
二里河金矿是近几年勘查探明的一个小型金矿床,全矿床共分2个矿段、6个矿带、11条金矿体,矿体数量多、分布分散、厚度小、品位低,没有主矿体。采矿表明,矿体的实际形态与勘查时圈定的矿体形态出入较大,实际采出的矿石量、品位都与预计的结果偏差较大,导致矿山无法正常生产。二里河金矿的采矿实践为以后金矿勘查、开发积累了经验,一定要按国家的规定、规范要求进行,以避免给国家和单位造成不必要的损失和浪费。
The Erlihe gole deposit was prospected and proved to be a small-scale gold deposit in recent years. The deposit is divided into 2 sections,6 ore belts,11 gold ore bodies,with many scattered low-thickness and low-grade ore-bodies without main ore body. Mining practice showed that the actual shape of ore body is much different from the ore body delineated in the prospecting stage. The actual exploited output and the grade of the ore are much smaller than expected with larger deviations,giving rise to abnormal operation. The mining practice in Erlihe gold mine provides experience for further prospecting and exploitation of gold deposit. National stipulations and specifications should be followed to avoid losses to the enterprises
