Abstract: Dust control at tunneling working face is the emphasis and difficulty in coal mine safety work and occupational health management of workplace. With the help of superior occurrence conditions of coal seam and the advanced equipment, Shendong Mining Area achieves rapid tunneling of roadway and forms the characters of large cross section excavation, high speed, high efficiency and producing large quantities of dust during tunneling. To solve these problems and ensure the safety production of working face, dust removal by ventilation technology is continuously researched at long distance and large cross-section roadway tunneling face in Shendong Mining Area. On the basis of long-term research, analysis, evaluation, a set of dust removal by ventilation technology suitable for Shendong Mining excavation work is successfully established, which makes the face dust concentration from more than 1, 000 mg/m³ conform to the requirements of occupational health of coal mine and meets air volume, wind speed and dust prevention and control requirements of tunneling working face in mining area and ensures safe, rapid, efficient production of tunneling work.
