摘　　要：为了解决综放工作面高浓度粉尘问题,通过对表面活性剂抑尘机理的分析,结合相同条件下不同表面活性剂及复配试剂的接触角、表面张力测定实验,优选出使用方便、抑尘效果好、价格低廉的新型复配抑尘剂,并利用风流增压式液体定量混合装置实现表面活性剂的定量动态混合。实践表明,该复配抑尘剂对工作面粉尘尤其是呼吸性粉尘有较好的抑尘效果。In order to solve the problem of high-concentrations dust in the fully mechanized caving face,the dust suppression mechanism of surfactants was analyzed,and a new cheap compound dust suppressant was preferred to facilitate the convenience of usage and better effects according to the surface contact angle and surface tension experiments of different surfactants and compound reagents under the same condition.Meanwhile,the airflow pressurized liquid mixing quantitative device was used to realize the quantitative dynamic mixing of the surfactant.The practices showed that this compound dust suppressant has a good suppression effect on the dust in the working face,especially on the respirable dust.
