摘　　要：对新型分段式注水封孔器在不同封孔注水压力条件下的注水时间,以及注水前、后粉尘浓度进行了现场实测分析。研究结果表明,分段式封孔注水时间随着注水压力增加而减小,随分段式封孔器的增加而增加;在司机处及其后10 m处测得,采用分段式封孔注水后的降尘效率分别达到66.5%、67.6%,取得较好的降尘效果。The on-the-spot measurement and analysis on the water infusion time under different hole-packing infusion pressure of the new sectional infusion hole packer and the dust concentration before and after water infusion were conducted.The research results indicated that the time of sectional hole-packing water infusion decreased with the increase of water infusion pressure and increased with the increase of sectional hole packers;after the sectional hole-packing infusion was adopted,the dust removal efficiency measured at the operator's location and the place 10m behind the operator respectively reached 66.5% and 67.6%,better dust removal effect was obtained.
