Based on large producing dust quantity of Fangezhuang Mine, Traditional long wall water injection effect was not satisfied because of coal seam, the application of short wall water grouting showed that drilling length of coal working face no more than 8 m, spacing no more than 15 m, Drilling length of heading face. no more than 12 m, with good water grouting and dust extinguishing effect, the technology controlled dust and reduced dust quantity, ensured safe mining.
