Abstract: In view of the problem that high concentration of dust generated during the excavation process of Baode Coal Mine, the dust reduction technology combined with large-diameter drilling coal seam water injection, anchoring machine spray block transformation, high-pressure external spray dust-reduction and wet drilling technology was proposed, at the same time, by combining the retractable full-section dust capture spray device and efficient cleaning technology for secondary dust removal, a set of comprehensive dust removal technology and process for heading face was established, which realized the low-dust production of heading face. The application results show that the water content of coal seam in heading face of 81310 belt transport roadway, 81311 return airway and crossheading in Baode Coal Mine increases by 3.82% on average after water injection, the average dust removal rate of total dust reaches 98.72%, and the average dust removal rate of respirable dust reaches 97.36%, which effectively improve the dust pollution condition of the working face and provide favorable conditions for safe and efficient production of the mine.
