The invention discloses a low-cost coal dust suppressant and a preparation method thereof. The low-cost coal dust suppressant comprises sodium carboxymethyl cellulose, sodium tetraborate, sodium sulfate, a corrosion inhibitor, polyacrylamide, a surfactant and water. The preparation method of the coal dust suppressant comprises the following steps: sequentially adding the sodium carboxymethyl cellulose, the surfactant, the corrosion inhibitor, the polyacrylamide, the sodium sulfate and the sodium tetraborate, and fully conducting stirring for 30 minutes to obtain powder; and adding the powder into water while stirring, and continuously conducting stirring for 20-30 minutes after the powder is completely added. According to the low-cost coal dust suppressant and the preparation method thereof provided by the invention, sodium tetraborate and sodium sulfate are added, so that the use of sodium carboxymethyl cellulose is reduced to a great extent, and the preparation cost of the dust suppressant is reduced. 本申请公开
