The invention relates to the technical field of germanium resource exploration, and discloses a drilling hole arrangement method for coal type germanium deposit exploration. The method comprises the steps that firstly, based on coal field exploration data, the positions of existing germanium mineralization holes and the position of a fault in the exploration range are obtained; then, based on thepositions of the existing germanium mineralization holes and the position of the fault, a plurality of first drilling holes are formed in the periphery of the fault; then, each nth drilling hole is subjected to coring, that the nth drilling hole is the nth mineralization hole is confirmed, a plurality of (n + 1) drilling holes are formed in the periphery of the nth mineralization hole, and nis accumulated from 1; and the n + 1 drilling holes reach the boundary of the exploration range or are non-mineralization holes. According to the drilling hole arrangement method, the drilling holes are formed according to the mineralization characteristics of a coal type germanium deposit, the arrangement density of the drilling holes is improved in a key area, the control degree in the coaltype germanium deposit exploration range is improved, the exploration precision is improved, the arrangement of unnecessary drilling holes is reduced, and the exploration cost is reduced.
