Abstract：This paper analyzed the generation cause of high-concentration dust in heading face, put forward the dust suppression technology by high-pressure external water spraying in dust concentration overrun, that is, combining the dust suppression technology by high-pressure external spraying on the heading machine with the dust suppression technology in dust concentration overrun. Through the combination of the dust suppression technology by high-pressure external spraying in dust concentration overrun with the seam water infusion under dynamic pressure, a complete set of dust suppression technology in heading face was formed. This dust suppression technology was applied in the heading face of 3115 southern haulage roadway, and the practice showed that the dust removal efficiency at the operator position in the heading face reached 90. 3% after the complex dust removal measures were applied, the dust pollution in the heading face was effectively improved.
