摘　　要：为准确有效评估矿尘抑制剂的抗风性能,采用单位质量抑尘剂平均风损率、平均抑尘率及临界有效质量3个评价参数,通过控制风速、吹蚀时间、吹蚀角度以及抑尘剂喷洒质量开展煤样风蚀模拟实验。结果表明:随着风速的增加,纯水和抑尘剂的单位质量抑尘剂平均风损率呈上升趋势,单位质量抑尘剂平均抑尘率呈明显下降趋势;随吹蚀时间延长,纯水和单位质量抑尘剂平均风损率呈上升趋势,单位质量抑尘剂平均抑尘率呈缓慢下降趋势;随着吹蚀角度的增加,单位质量抑尘剂平均风损率呈先下降后上升的趋势,在60°时达到最低,单位质量抑尘剂平均抑尘率先上升后下降;当抑尘剂喷洒质量达到临界有效质量时,抑尘效果最佳。This study proposes three evaluation indexes for evaluating the wind resistance of mine dust inhibitors,namely average loss rate per unit mass(ALRPUM)of dust suppressant,average suppression rate per unit mass(ASRPUM)of dust suppressant,and critical effective mass(CEM).The wind tunnel simulation experiment was carried out on coal samples by controlling wind speed,blowing time,blowing angle,and spraying quality of dust suppressant.Results show that the increase in wind speed leads to an increase in the ALRPUM of dust suppressant and pure water,and a significant decrease in the ASRPUM.The increase in blowing erosion time also leads to an increase in the ALRPUM of dust suppressant and pure water,while the ASRPUM of dust suppressant shows a slow downward trend.With the increase of blowing angle,the ALRPUM of dust suppressant exhibits a trend of initially decreasing and then increasing, reaching its minimum at an angle of 60°. The ASRPUM of dust suppres-sant shows an initial increase and subsequent decrease. The dust suppressant reaches its maximum effect when the spraying quality of the dust suppressant reaches the CEM.
