Abstract

With the development of large-scale coal mining equipment, fully-mechanized mining faces with 8 m or higher mining height have been applied successfully. However, the increase in yield and mining space makes it difficult for traditional dust prevention techniques to handle dust pollution issues. In order to solve this problem, a method of dust removal by ventilation was creatively proposed for fully-mechanized mining faces. Also, exemplified by the 12513 fully-mechanized mining face of Bulianta Coal Mine, a numerical calculation model was established. By combining theory, numerical simulation and field test, an “onboard dust removal” technology was proposed and a dust collector mounted on the coal cutter was developed. Besides, with numerical simulation and industrial field experiment, it was validated that the proposed technology could reduce the dust particle mass concentration near the sidewalk by 77.2% with a comprehensive average dust suppression efficiency of 74.25%. It provides a practical basis for creating a green and safe production environment in coal mines.
