摘要

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0.4 mPa·s，保水率为80.5%，降尘效率可达95.3%。

Abstract:
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%.
