In order to improve the quality and efficiency of gas concentration monitoring in coal mine roadway inspections,avoid gas outburst and explosion risks,and reduce personnel input,an intelligent inspection robot for coal mineroadways was studied.The structural composition and parameter design of the intelligent inspection robot were introduced,and the key technology of ultrasonic diffraction time difference positioning applied in the intelligent inspection robot was elaborated.Through on-site testing in coal mines,it had been shown that the intelligent inspection robot could accurately measure gas concentration on site,reduce personnel input by 67 people,and save a total annual expenditure of about 7.23 million yuan.It had played a substantial role in reducing costs and increasing efficiency,and helped to promote the high-quality development of intelligent construction in mines.
