摘要
本文对急倾斜密集型复杂的脉状矿床,矿脉数2—3条,脉宽1—3米,平均2.5米,脉间夹石厚度3米,开采中采用了条脉分采夹石保留的留矿法开采,实践证明经济效果明显,方法可行.
This paper has made a description of the mining practice of complex deposit of steep dip and close-set lodes in Hong-Tou-shan Copper Mine.There are 2 or 3 close-spaced lodes Underground with 1-3 meters in width (the average is 2.5 meters). In the mining operation, the shrinkage method was opted to mine these lodes one by one with intercalated bed remained.It was improved that this mining method was practical with obvious economic benefit.
