摘要
桃江王家冲中型锑矿床,赋存在上元古界板溪群五强溪组中段灰绿色板岩中,背斜翼部的层间剥离、破碎裂隙是矿床形成的储矿构造,东西向断裂V_4、V_5为控矿构造。矿区一般见2~3层矿,平均厚度1.24m,平均品位Sb4.98%。矿石矿物主要是辉锑矿。矿床成因属燕山期中低温液型锑矿床。该矿床已有70年开采历史,去年曾出现资源危机,矿山面临关闭。笔者应邀赴矿对井下未知矿体进行预测,旨在指导生产找矿。由于科技咨询与生产找矿紧密结合,短时间内就取得了找矿突破,解了矿山燃眉之急,延长了矿山生产服务年限,社会经济效益明显。
Wangjiacong antimony mine in Taojiang county,a middle size deposit,occurs in the gray- green slate of the middle part of Wuqiangxi formation of upper Proterozoic Era,the Banxi group.The interstrat- ified desquamation develops in flanks of the anticline and the broken tense fractures play an important role of ore accumulation structure. The deposit is controlled by east west trending faults V_4, V_5. Generally 2 or 3 layers have been seen in the mine with average thickness and content of Sb,1.24m and 4.98%respectively.of ore minerals antimonite is predominant.The origin to whech the depositt belongs is a meso-epithermal mineraliza- tion of Sb.Wangjiacong mine has a mining history of 70 years. Unfortunately,last year it met a crisis of mineral re-sources that made the rnine face to be closed.With the invitation of the mine author went to there to give a prog- nostication of the hidden ore bodies in shafts,aiming to guide the mining and to verify the theory of prospecting. It is due to the ciose combination of scientific and technologic consultant and the prospecting that a breakthrough in ore-searching was obtalned within very short time. Now the urgent situation of mine is released.That has not only saved the mime, but also prolonged the service period of it.In short, this is an encouraging achievement with conspicuously social and economic efficiency.
