Dust-settling method of working face for layered and fully-mechanized coal mining of gently-declined thick coal seam by water injection under dynamic pressure

The invention discloses a dust-settling method of a working face for layered and fully-mechanized coal mining of a gently-declined thick coal seam by water injection under dynamic pressure. The methodcomprises the following steps of drilling a sealing-tape machine crossheading and an air return crossheading in the two sides of the coal seam respectively, and getting through and connecting the tail ends of the sealing-tape machine crossheading and the air return crossheading to form the working face used for fully-mechanized coal mining; conducting drilling at intervals in the sealing-tape machine crossheading and the air return crossheading in the length direction of the sealing-tape machine crossheading and the air return crossheading to drill out spaced dynamic pressure holes I, and filling the dynamic pressure holes I with cut-off devices I used for sealing the radial direction of the dynamic pressure holes I; injecting safe gas in the dynamic pressure holes I through the cut-off devices I according to a predetermined exhaust rule, and then replacing hazardous gas in the dynamic pressure holes I with the safe gas through the cut-off devices I; using the safe gas to sufficientlyopen up the intervals according to the predetermined exhaust principle to avoid the situation that the hazardous gas drifts away, causing decompression and accompanying compaction effect; and meanwhile, the hazardous gas and safe gas are mixed to constantly and continuously dilute the concentration of the hazardous gas, and therefore, the aggregation effect of the hazardous gas is reduced to a great extent.
