摘　　要：以某煤矿掘进工作面粉尘为研究对象,开展矿井高效抑尘剂优化配方及性能研究。通过沉降实验,确定高效抑尘剂优化配方的润湿剂组分为2%的TX-100和0.5%的SDBS混合溶液;通过黏度测定实验,确定优化配方的黏结剂组分为E412;通过保水性实验,确定优化配方的保水抑尘剂组分为PAAS;通过抑尘剂溶液的酸碱度测定实验,确定选用PHOS调节溶液的pH值为6.8;最终研究得到矿井高效抑尘剂GHY-1配方组分及比例。性能测定实验结果表明:高效抑尘剂优化配方表面张力为68.15 mN/m,左、右接触角分别为11.25°和10.85°,黏度值为0.4mPa·s,保水率为80.5%,降尘效率可达95.3%。Taking the dust of a coal mine driving face as the research object,the optimization formulation and performance of highly effective dust suppressant were studied.Through sedimentation experiments,the wetting agent components for optimizing the formula of high-efficiency dust suppressants were determined to be a mixture of 2%TX-100 and 0.5%SDBS solution;by conducting viscosity measurement experiments,the adhesive component for optimizing the formula was determined to be E412;by conducting water retention experiments,the water retention agent component for the optimized formula was determined to be PAAS;through the experiment of measuring the acidity and alkalinity of the dust suppressant solution,it was determined that the pH value of the solution adjusted by PHOS was 6.8;the final research obtained the composition and proportion of the high-efficiency dust suppressant GHY-1 formula for mines.The performance measurement experiment results show that the optimized formula of high-efficiency dust suppressant has a surface tension of 68.15 mN/m,the left and right contact angles are 11.25°and 10.85°,respectively,viscosity value is 0.4 mPa·s,water retention rate is 80.5%,and dust reduction efficiency is 95.3%.
