The invention discloses a mineral resource exploration multi-dimensional analysis processing system based on the Internet of Things and feature recognition, and the system comprises an open-pit mine preliminary exploration module, an open-pit mine basic parameter obtaining module, an open-pit mine region division module, a region mineral depth exploration module, a mineral parameter database, an analysis cloud platform, and a background display terminal. According to the method, preliminary mineral resource exploration is carried out on a mine in an unmanned aerial vehicle prospecting mode so as to find out the geographic position of an open-pit ore deposit, region division is carried out on the open-pit ore deposit, appearance feature extraction is carried out on all ores in each divided ore deposit sub-region so as to screen out useful ores, and therefore, the distribution condition of the internal components of the screened useful ore is obtained by using an X-ray detector, so that the comprehensive storage coefficient of the mineral resources corresponding to the open-pit ore deposit is counted, the exploration efficiency is improved, a large amount of manpower exploration cost and material exploration cost are saved, and the exploration level is improved.
