摘要/Abstract

摘要：

干河坝金矿床产于勉略康构造混杂岩带中，矿体表现为产于剪切带中的一系列断续分布的透镜体，单矿体走向长50~150 m，矿床类型属于剪切带控制的微细浸染型金矿。先期勘探中，由于未发现矿体侧伏规律，导致很多勘探钻孔未见矿，认为矿体深部延伸有限，因此，将干河坝金矿规模定为小型金矿。通过近几年的矿山开发和勘探实践，发现金矿体为一系列向东侧伏的矿柱，侧伏角40~55°，单矿体延深远大于延长，工程控制矿体垂深＞300 m。同时，运用矿体向西复侧伏的规律，进行矿区深部及外围探矿，取得很好的找矿效果，极大地节约了勘探成本。在总结矿体侧伏规律和最新勘探进展的基础上，重新认识矿区的资源潜力，认为干河坝地区具有形成中—大型金矿的找矿前景。

Abstract:

Ganheba gold deposit occur in Mian -lue tectonic mélange belt,it is a fine disseminated gold deposit hosted by shear zone.Gold orebodies are characterized by a series of discrete lenses within shear zone,and individual ore body is 50 to 150 meters in strike length.A lot of dill holes did not encounter the ore before，because the downplunge law was not discovered at that time,thus considered the down dip content is limited and thought Ganhebai gold deposit as a small deposit.After several years mining and exploration experience in recent year,found orebodies were expressed by a series of ore shoots that plunge to east at 40~55°,and the down dip content of individual ore shoot is more longer than its strike length,the ore shoot vertical content controlled by workings is over 300 meters and still open.At the same time,the multi-side-pitching law was recognized,subsequently the downplunge and muti-downplunge law were applied in deep depth and peripheral exploration,resulted in a very good exploration result and dramatical decrease of exploration costs.Based on the downplunge law of ore shoots and the new exploration progress,the exploration potential was reconsidered,we suggest Ganheba district has a good exploration prospect to become a medium-big sized gold deposit.
