鉴于普通水炮泥在井下爆破降尘和减少炮烟效果不佳,采用表面活性能和界面能理论,对水炮泥添加剂进行筛选和正交复配试验,比较加有不同种类表面活性剂的溶液的表面张力和润湿速度,以改善水炮泥添加剂配方。将所得的高效水炮泥在典型煤矿进行现场试验。结果表明:自配表面活性剂P3的正交复配质量分数为0.05%时溶液的表面张力最低,润湿速度最好。高效水炮泥可提高溶液的润湿、分散、吸附以及增稠的能力;新配方的高效水炮泥对呼尘和全尘的相对降尘率分别为62.08%和64.54%。
In view of the ordinary shotgun blasthole dust in the downhole and to reduce the effect of poor smoke, the use of surface activity and interface energy theory, water cannabis mud additives screening and orthogonal test, compared with different types of surfactant solution The surface tension and wetting speed to improve water gun mud additive formula. The resulting high-efficiency water cannons in a typical coal field test. The results showed that the surface tension of solution was the lowest and the wetting speed was the best when the content of self-formulated surfactant P3 was 0.05%. The efficiency of water cannlar mud can improve the wetting, dispersing, adsorption and thickening ability of the solution. The effective dusting rate of dusting and dusting by the new formula water cannlar mud is 62.08% and 64.54% respectively.
