Abstract: Based on technical problems such as high dust concentration , poor dust suppression effect of spray sprinklers, serious
hydrostatic water loss during the stoping period of 1207 working face, this paper proposed the combined dust prevention technology
of "coal seam staggered stepping drilling water injection + installation of full-face automatic circulation dust-proof water curtain
+ installation of rotating foam dust suppression device". After practical application, the average dust mass concentration at the
coal landing point of the working face dropped to 56 mg/m³, and the average dust mass concentration in the transportation trough
dropped to 39 mg/m³, which achieved significant application results.
