Research and Application of Prospecting and Mining Combination Technology in Poor Ore in the East of Jinchuan No.3 Mine Area
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.
