| Abstract: | Based on the analysis of dust-producing characteristics in fully-mechanized caving face in three-soft thick coal seam and to counter the dust control situation in 12202 working face in a mine of Zhengzhou Coal Industry(Group) Co.,Ltd.the complex dust control measures including water infusion in coal seam,high-pressure spray and dust-blocking net were used to control the dust produced in the process of coal mining.It was found in the examination of the dust control effect that the comprehensive dust suppression rate reached 85% or more,so this can provide a certain reference for the dust suppression and control of the working face in three-soft seam. |
