  • Based on field measurement and analysis of dust dispersity in Pinggou coal mine fully mechanized coal face,conclusions on dust dispersity was obtained.Near the dust source the dust size are average,large particle dust accounts for large percentage.Near the floor composed mainly of large particle.With the increase of the distance with the dust source the dust size are tended to be stable,mainly with the fine particles which are hard harm to human body.It is show that fine particles are hard to… CONTINUE READING
