深水潭金矿床成矿后期断裂构造研究对矿山实际生产的作用

Effect of research on fault structure of Shenshuitan Gold Deposit in late metallogenic stage on actual production of mine

深水潭金矿床为位于青海省都兰县五龙沟地区,矿床成因类型为中低温岩浆热液型破碎蚀变岩型金矿,区内现已发现金矿体走向、倾向延伸严格受控于主破碎蚀变带,地质勘查阶段由于投入的坑探工程有限,未能系统的揭露成矿后期断裂构造,矿山生产过程中,通过利用开拓工程、采准、采切工程揭露验证。矿床发育成矿后期断裂构造,对矿体的破坏作用较大,给探矿工程布设和矿体圈连工作带来了极大的困难,通过探讨成矿后期断裂构造在空间展布规律,为矿山探矿工程的布设、矿体圈连提供积极的指导作用,为后期该区及周边的金矿勘查提供参考。

The Shenshuitan Gold Deposit is located in Wulonggou Area,Dulan County,Qinghai Province.The genetic type of the deposit is a medium-low temperature magmatic hydrothermal type fractured altered rock type gold deposit.The strike and trend extension of gold ore bodies have been discovered in the area under strict control in the main fracture alteration zone,due to the limited pit exploration project invested in the geological exploration stage,the fault structure in the later stage of mineralization could not be systematically exposed.During the mine production process,it was verified through the use of development engineering,mining standard,and mining and cutting engineering.The ore deposit developped fracture structures in the later stage of mineralization,which had a greater destructive effect on the ore body,which brought great difficulties to the layout of prospecting projects and the connection of ore bodies.The layout of prospecting projects and the connection of ore bodies provided active guidance,and provided reference and reference for later gold prospecting in this area and surrounding areas.
