摘　　要：在黔中地区浅部铝土矿资源即将勘查殆尽的前提下,研究和探索该地区深部铝土矿资源潜力,提高铝土矿资源的保证程度,对保障贵州铝工业的可持续健康发展和国家战略资源安全具有重要的意义。贵州省清镇市汪家寨铝土矿普查1300 m深钻为黔中地区首个千米级钻孔探索该区铝土矿资源的深钻,实现黔中铝土矿埋深大于1000 m隐伏矿的找矿突破,为黔中地区深部铝土矿成矿理论研究及找矿潜力提供有利的地质钻孔和实物岩心资料。为扩大区内铝土矿深部找矿潜力,降低找矿风险,实现老矿区深边部找矿突破,文章通过对黔中地区汪家寨铝土矿床地质特征、深部成矿条件预测、实施深孔验证过程及取得成果的分析,总结了黔中地区铝土矿深部找矿的有利组合因素,并指出黔中地区已知铝土矿矿体深部未圈边,且已知信息判断矿体连续,在其倾向延伸方向的三叠系空白区深部仍具有非常大的铝土矿找矿潜力。Under the premise that the shallow bauxite resources in Central Guizhou are about to be depleted out,there is a great significance to study and explore for the potential of deep bauxite resources in Central Guizhou and to improve the guarantee degree of bauxite mineral resources for the sustainable and healthy development of aluminum industry in Guizhou and the security of national strategic resources.For the geological survey at Wangjiazhai bauxite mining area in Qingzhen City of Guizhou Province,the first kilometre-level drilling hole of 1300 m depth is carried out to explore for the bauxite orebody in the mining area,the exploration breakthrough achievement of hidden bauxite orebodies has been realized with one deep drilling hole more than 1000 m in Central Guizhou,and the favorable geological drilling and physical core data are provided for the deep bauxite metallogenic theoretic research and prospecting potential in Central Guizhou.In order to expand the prospecting potential of bauxite deposit in the deep area,and to reduce the prospecting risk,and to achieve the prospecting breakthrough at deep edge area of the old mining area,this paper summarizes the favorable combination factors of deep prospecting of bauxite deposit in Central Guizhou through the analysis of geological characteristics,prediction of deep mineralization condition,implementation of deep drilling verification process and achievements of Wangjiazhai bauxite deposit.It is also pointed out that the bauxite orebody in the mining area has not the deep edge,and the known information indicates that the bauxite orebody is continuous,and there is still a very great prospecting potential of bauxite resources at the deep part of Triassic blank area in the direction of its dipping extension.
