摘　　要：近年来,我国许多大中型有色金属矿山经过多年开采后,出现资源严重不足.文章主要针对危机矿山——湖南省锡矿山锑矿的现状,探讨寻找接续资源的问题,以期在危机矿山深边部取得找矿突破.在锡矿山北部的稻草湾矿区共布设11条可控源音频大地电磁测深法(CSAMT)剖面,通过对探测数据进行预处理、静态校正以及二维反演计算等方法,研究该区受断裂和地层联合控制的隐伏锑矿体的存在状态.研究成果突显了稻草湾矿区控矿断裂的分布特征,并由此推断出隐伏矿体的标高位置.经后期钻孔验证可知:CSAMT的解译结果与断裂构造和矿体的位置吻合,表明CSAMT法在该区找锑具有较好的效果,可为今后类似的危机矿山深边部找矿提供科学依据.In recent years,many large and medium-sized non-ferrous metal mines in China have experienced severe resource shortages after years of mining.Focusing on the current situation of the crisis mine,i.e.the Xikuangshan Antimony Mine in Hunan Province,the paper attempts to achieve breakthroughs in mineral exploration in the deep edge of the mine and find continuing resources.Eleven controlled-source audio-frequency magnetotellurics(CSAMT)profiles are laid out in the Daocaowan mining area in the northern part of Xikuangshan Mine.By means of pre-processing,static correction and two-dimensional inversion,the existence state of buried antimony orebody controlled by faults and strata in this area is studied.According to the research results,the distribution characteristics of ore controlling faults in the Daocaowan mining area have been highlighted,and the position of hidden ore bodies has been inferred.The later drilling verification shows that the interpretation results of CSAMT are consistent with the actual situation,such as the positions of fault structure and ore body.The research results indicate that the CSAMT method is effective in prospecting antimony in the area,and can provide scientific basis for future exploration of similar crisis mines in the deep edge.
