First, the inventor proposed a technical feature of long-distance wind-carrying transportation of the dry coal powder generated by the pressure relief drill rig, and obtained the first unexpected technical effect: the dry coal powder generated by the pressure relief drill rig is transported in a non-retention state, ensuring that the working environment of the pressure relief drill rig is no longer polluted. The second unexpected technical effect is achieved: mobile movement in the working place of the pressure relief drill rig is achieved, and mobile matching with the crawler-type pressure relief drill rig is achieved, thereby improving the efficiency of drilling pressure relief holes. The third unexpected technical effect is achieved: the blower-type output of the wind body is achieved, ensuring the stable transportation performance of the wind body. The fourth unexpected technical effect is achieved: the falling-type fusion of the dry coal powder generated by the pressure relief drill rig with the wind body is achieved, thereby improving the blowing force on the dry coal powder generated by the pressure relief drill rig. The fifth unexpected technical effect is achieved: remote transportation by the powder conveying pipe located in the coal mine is achieved, eliminating the generation of powder fog in the coal mine.
