银洞坡金矿区东段地质储量负变原因分析

Analysis of the reasons of negative boosting of geological reserves in the east part of Yin Dong Po gold mining area

论文从矿体圈定运用的原则不合理，地质探矿网度大，储量级别偏低与金的富集规律的不对应性，传统储量计算方法及对特高品位的处理不妥当，计算储量依据的钻孔资料缺乏代表性、可信度低等几个方面分析了造成银洞坡金矿区东段地质储量负变的原因。

This paper makes an analysis of the reasons of negative boosting of geological reserves in the east part of Yin Dong Po gold mining area.The reasons include such things as the unreasonable option of the orebody’s mining principle,the long intervals between geological prospectings,the low grade of ore reserves which are not correspondence with gold concentration regularity,the inproper calculation of extra high grade ore reserve by using traditional calculation method,the drill hole data which are not representative yet used as the bases of calculating ore reserves and so on.
