Abstract: To solve the key problems that restrict the breakthrough in mining exploration,the theory and methods of prospecting prediction in the exploration area were applied,and the special three-dimensional spatial structure-alteration geological mapping of the mining area was carried out,which dissected typical deposits and focused on study-ing the mineralization structure and mineralization structural surfaces of the Taibai Gold Deposit (breccia-type gold deposit),clarified the mineralization structure system in the mining area,and constructed the spatial framework basis of the mineralization structure.By sorting out and summarizing the mineralized geological body,mineralization structure and mineralization structural surfaces,and the characteristic markers of mineralization of the Taibai Gold Deposit,a preliminary trinity prospecting prediction model was constructed.Combined with the structural primary halo measurement results,5 prospecting targets and 3 areas with prospects were delineated.Among them,one prospecting target was verified through engineering exploration,indicating that the trinity prospecting prediction model has a good prediction effect and practical guiding significance for mining exploration in the mining area.
