摘　　要：为有效降低10-428B工作面粉尘浓度,根据工作面开采条件和采煤机现场布置情况,设计采用液压支架风助集中喷雾降尘+采煤机湿式风助降尘相结合的降尘方法。现场应用结果表明:采用上述降尘方法后,工作面各个区域全尘和呼尘的降尘率均在80%以上,降尘效果较显著。To effectively reduce the dust concentration of 10-428B working face,with accordance to the mining conditions of the working face and the site layout of the shearer,a dust reduction method of“hydraulic support wind-assisted centralized spray dust reduction+coal shearer wet wind-assisted dust reduction”is designed in the paper,whose field application results show that after adopting the dust reduction method afore mentioned,the dust reduction rate of all dust and respirable dust in each area of the working face is above 80%,which proves significant dust reduction effect.
