According to the obtained results of mine deep exploration，the systematic collection of geological exploration as well as scientific research achievements in the study area，in the process of project implementation for the old mine deep prospecting nationwide，it was found that gold grade of the deep gold-silver vein exhibited a rising trend at the Qiliping F60-I gold and silver orebody.Through study on occurrence of state of the known orebody，regularities of distribution and ore-forming characteristics，deep tectonic mineralization，ore-controlling characteristics and metallogenic elements were analyzed.Additionally，based on MapGIS DTM spatial data analysis，the weight contour was applied for predicting space extending trend of the ore body，moreover，the state of the three-dimensional space of the ore bodies was likewise systematically studied.Reference for ore body engineering validation effect，the orebody spatial prediction scheme and validation project were adjusted and a good prediction effect was obtained.Meanwhile，we achieved the old mine deep ready exploration prospecting breakthrough，which had the very good guidance significance and demonstration effect deep prospecting engineering deployment for the deep prospecting in Xiaoqinling area，and it can effectively promote the deep geological prospecting work of the implementation and exploration engineering in the study area.
