Regarding to the limitations of several existing coal mine Measurement-While-Drilling (MWD) data transmission modes in practical application, this paper aims to achieve the application of the acoustic wave transmission technology in coal mine MWD system by using propagation characteristics of the acoustic wave in the drill pipe so as to make up for the application deficiencies of existing transmission modes in the working condition. In this paper, the attenuation and adaptative frequency of the signal in the drill pipe column are verified by the mathematical analysis of the acoustic wave propagation characteristics in the drill pipe column, the signal sources and communication strategies that meet the conditions of underground coal mine are designed, and the communication effect of the acoustic wave in the drill pipe string is verified through testing MWD data transmission, which proves the feasibility of the data transmission through acoustic wave in underground coal mine.
