At present, the face of rock drift driving face is based on wet rock drilling comprehensive dust control measures, this measure compared with the dry eye, the dust effect is significant. However, the blasting process still produces a lot of dust, the highest up to thousands of milligrams / m ~ 3, has indeed become a comprehensive dust control measures the most difficult problem. To this end, we conducted a preliminary hygiene appraisal on the dust-reducing effect of the current Fengshui double-tube atomizer in the Central Taiwan Coal Mine. Now the results are as follows:
