The invention provides a preparation method of a wear-resistant alloy material, which comprises the following steps: manganese slag is heated in an aerobic environment to obtain solid slag rich in manganese dioxide; carbon powder or ferrosilicon is added into the solid slag rich in manganese dioxide, and carrying out high-temperature reduction smelting is performed to obtain a manganese-rich alloy; the manganese alloy and the ferrotungsten alloy are mixed according to a set proportion to obtain a premix, and the premix is subjected to high-temperature smelting to obtain the ferrotungsten manganese alloy; and the tungsten-iron-manganese alloy is poured into a mold to form a blank, and the wear-resistant alloy material is obtained after the blank is subjected to a heat treatment process. According to the preparation method of the wear-resistant alloy material, the carbon powder or the ferrosilicon alloy is added into the manganese dioxide obtained by heating the manganese slag in the aerobic environment, and th
