摘 要:针对首山一矿综采面喷雾用水湿润性能差、雾化捕尘效率低的问题,提出了综采面活性磁化水喷雾降尘技术。实验测试了活性磁化水所具有的强湿润性能,其接触角、粉尘沉降时间及降尘效率相对于纯水都得到了大幅度的提高,同时提出了活性磁化水高效制备工艺。经首山一矿12100综采工作面应用表明:活性磁化水喷雾降尘技术能有效降低工作面粉尘浓度,不同测点呼吸性粉尘、全尘平均降尘效率分别达到了84.67%、88.52%,有效改善了井下职工工作环境。Aiming at the poor dust control efficiency and wettability of the solution spray in the fully mechanized mining face,the dust control technology using surfactant-magnetized water was proposed.The strong wetting properties of the surfactant-magnetized water were measured,including the contact angle,dust deposition time and dust control efficiency,which were greatly improved than that of the untreated water.Meanwhile,the preparation process of the surfactant-magnetized water was put forward.The field application results in the 12100 fully mechanized mining face,Shoushan No.1 Mine showed that the dust removal technology using surfactant-magnetized water can effectively reduce the dust concentration in the working face.The average dust removal efficiency of respirable dust and total dust at different measuring points was 84.67% and 88.52%,respectively,the underground working environment was greatly improved.
