摘　　要：针对目前煤矿爆破除尘消烟剂效率低、原材料不易获得、价格昂贵等缺点,采用均匀设计方法确定试验配合比,研制出了一种高效爆破除尘消烟剂。该除尘消烟剂由吸湿剂、表面活性剂、消烟剂、缓蚀剂等组成。以这4个因素作为变量,利用均匀设计3.0软件对除尘率和消烟率进行逐步回归,得到回归方程;然后在此基础上进行优化,求出给定现场试验条件下除尘消烟的最优值。优化后的水溶液质量配比组合是:吸湿剂5%、表面活性剂1%、缓蚀剂0.4%、消烟剂0.2%。应用试验表明,该除尘消烟剂能够方便高效地降低煤矿井下爆破产生的有毒粉尘和烟雾,在安全环境领域具有广泛的应用前景。In view of the deficiencies of current dust and smoke suppressors for coalmine blasting, such as low efficiency, difficult acquisition of raw material and high price, a kind of high-performance formulation of dust and smoke suppressor is developed by using uniform design method to decide the mixing proportion, which is composed of hygroscopic a- gent, surfactant, smoke suppressor and corrosion inhibitor. Taking these 4 elements as variables, a regression equation for dust and smoke suppression coefficients is obtained by stepwise regression method based on 3.0 version software for uniform designing. On this basis, the optimal value of dust and smoke suppression coefficients is found under given experimental conditions. The optimized formulation of aqueous solution is ： hygroscopic agent, 5% ; surfactant, 1%, erosion inhibitor 0.4% ; and smoke suppressor 0.2%. Application tests indicate that this kind of agent can effectively and conveniently sup- press the poisonous dust and smoke produced in coalmine blasting, and will have an extensive application prospect in safety and environment field.
