摘要
银山地区自古就是我国著名的白银产地之一,开采历史悠久,作为铅锌矿为主的多金属开采利用最早上溯至上世纪七十年代。银山地区铅锌矿经过不同时期开发利用。矿权经过整合停产等历史变迁,使该区铅锌矿勘查呈现出极其复杂的特点。其复杂性主要体现在高程分段及不同的勘查分类(100中段米以上主要为核实;100-+57中段主要为核实及重算;+57中段以下主要为详查);多金属(铅锌、金、银、镉、铁、锰及氧化铅锌矿等);分品级(Pb+Zn≥5%时,圈定为高品位工业矿体;5%<Pb+Zn≥3%者圈定为低品位矿体;)
The Yinshan area since ancient times is one of the famous silver producing areas in China,has a long history of mining,as the lead zinc ore based multi metal mining using the first morning back in 70 s.Yinshan Lead-Zinc Mine Area after the development and utilization of different periods.The historical changes of the mining rights,such as the integration of production and so on,make the exploration of lead-zinc mine in this area show the extremely complex characteristics.Its complexity is mainly reflected in the segmentation and classification of different elevation survey(100 meters above the middle for verification;100-+57 the major for the verification and recalculation;+57 below the middle of the main survey);multi metal(gold,silver,lead and zinc,cadmium,iron,manganese and zinc oxide ore etc.);grade(Pb+Zn = 5% when the fence for the high grade industrial orebody;5% Pb+Zn 3% were delineated as low grade ore);
