摘　　要：柏杖子金矿床是辽西地区典型的岩浆热液型金矿床。柏杖子金矿原以石英脉型金矿体为主要开采对象,但近年来随着大量探矿工程的投入,发现了蚀变花岗岩型金矿体,且目前矿山以蚀变花岗岩型金矿体为主要开采对象。通过对矿区水文地质、工程地质、环境地质等开采技术条件进行重新总结与评价,认为矿区开采技术条件复杂程度均为中等。因开采矿体类型发生改变,导致矿床开采技术条件也在逐年变得复杂,由简单型变为Ⅱ-2类型,再由Ⅱ-2类型进一步变化为Ⅱ-4类型。Baizhangzi Gold Deposit is a typical magmatic hydrothermal gold deposit.In the past,the main mining object of Baizhangzi Gold Mine is gold-bearing quartz vein type gold ore bodies.However,with more prospecting projects joining in,alteration granite type gold deposits are found and have become the main mining object of the mine.The paper re-summarized and re-assessed the hydrogeology,engineering geology and environment geology in the mi-ning district,and concluded that the complexity of the mining technical conditions is in medium class.The technical conditions have been becoming more complex over the years because of the ore body type shift,in a process from simple type to Ⅱ-2 type,and further from Ⅱ-2 type to Ⅱ-4 type.
