摘要
铜坑矿地质工作者在前人研究的基础上,对多年来探采的井下地质资料进行了综合整理及对比分析,发现该矿体主要受泥盆纪硅质岩、层间裂隙和NE向节理所控制,东侧的花岗斑岩不是矿体的边界,而是错断了矿体.因此,在花岗斑岩东侧开展了坑钻结合勘查,新增锡多金属矿体(333)矿石资源量55万t.实践证明,花岗斑岩东侧找矿前景广阔,是今后找矿的主要方向.
Abstract
Based on the previous studies,the geological data of underground exploration in years were comprehensively sorted out and comparatively analyzed by the geologists of Tongkeng Mine.It was found that the ore was mainly affected by the Devonian siliceous rocks,interlayer fractures and NE joints;the east granite porphyry was not the boundary,but the broken orebody.Therefore,exploration with gallerydrilling combination method was carried out in the east of granite porphyry,and found 550,000 t ore resources of tin polymetallic ore body (333).Practice proved that the east granite porphyry,having broad ore prospect,was the main direction for future prospecting.
