摘　　要：为解决因矿山基建不具备探矿工作条件,造成矿体形态无法准确把握,影响矿山回采等问题,以金川三矿区东部贫矿首采1330分段为例,选取探采结合技术,以采准工程为先导并辅以地质勘探工程,通过取样化验分析、地质编录等手段,对东部贫矿地质界线变化、矿体规模形态、夹石带形态以及经济和社会效益进行研究。结果表明,探采结合技术能够有效探明地质界线变化情况,更正矿体规模形态及夹石带形态,提升出矿品位,获得较大经济效益及社会效益。In order to solve the problem that the ore body form cannot be accurately mastered due to the lack of conditions for the mine infrastructure exploration work,to effeet mining,taking the first mining section 1330 of the eastern poor ore in Jinchuan No.3 mining area as an example,the combination of explo⁃ration and mining technology is selected,the mining preparatory project is guided by the geological explora⁃tion engineering,and the sampling,laboratory analysis,geological cataloging and other means are adopted.The change of geological boundary,the size and shape of ore body,the shape of rock belt and the economic and social benefits of the eastern lean ore are studied.The results show that the combined exploration and mining technology can effectively detect the change of geological boundary,correct the size and shape of ore body and the shape of rock belt,improve the ore grade and obtain greater economic and social benefits.
