| Abstract: | Based on the study on the permeability of 9 # coal seam of GuanDi coal mine,a protocol and parameters for pressured water infusion into coal seam were proposed,and had been experimented at this mine.As a result,the coal dust concentration was reduced for more than 60%.It is meaningful for water infusion into coal seam and in suppression of the coal dust in underground pit in this country.
