The discovery of Baixintan copper nickel mine in East Tianshan, Xinjiang has expanded the space for searching for copper nickel mine in East Tianshan. However, due to the thick surface coverage, the spatial variation of the deep ore body of Baixintan copper nickel mine is large. It has been found that the deep ore body of Baixintan copper nickel mine is mainly distributed at a depth of less than 150 meters. Previous geophysical exploration work has shown that the shielding effect of surface saline alkali crust on electrical exploration is obvious. This leads to the failure of geophysical exploration to effectively describe the deep spatial distribution of ore bodies, which is not conducive to the development of deep prospecting prediction and further rating. Through the test of geophysical exploration method, this study selects the symmetrical quadrupole sounding in the conventional DC method, carries out the borehole sounding, selects the characteristic point method to judge the distribution form of copper nickel ore body within 0~500 m, and establishes a three-dimensional geophysical exploration model to predict the unknown and deep ore bodies, which can effectively guide the further prospecting direction of Baixintan copper nickel deposit and provide geophysical basis for the exploration of copper nickel deposits distributed in Baixintan area. <摘要译文>
