摘　　要：某金属矿位于哈密东部星星峡附近,地表出露主要为花岗岩,矿区内水资源匮乏,供水问题已成为影响企业生产的一项重大问题。为解决企业用水困难问题,寻找断层导储水有利位置,在遥感推测断层处,开展3条瞬变电磁测量,经处理分析发现断层附近200 m以浅区域存在低阻异常区,推测断层附近200 m以浅区域具备储水条件。后期在选定区域钻探打井,出水量为30 m^(3)·h^(-1),极大地解决了矿区用水需求。此次勘探查明了断层储水有利位置,选定了钻井位置,出水量满足矿方需求,解决了缺水问题,为类似地区解决用水问题开展水资源调查提供了借鉴意义。A metal mine is located near Xingxingxia to the east of Hami,with granite exposed on the surface.The water resources in the mining area are scarce,and the water supply has become a major problem affecting the production of enterprises.In order to solve the water use difficulties of enterprises,and find the favorable ground water fault,three transient electromagnetic exploration lines were arranged along at the remote sensing inferred fault.After processing and analysis,found a low resistance abnormal area being discovered in the depth above 200 m near the fault,and it was inferred that the shallow area 200 m underground near the fault water maybe existed.Later,drilling in the selected area,disclosed the ground water with the output of 30 m^(3)·h^(-1),which meets the water demand of the mining area.This exploration application provided reference for the investigation of water resources in similar areas to solve the water use problem.
