新型高分子抑尘剂对岩性颗粒物的抑制特性研究

Research on the inhibitory characteristics of new polymer dust suppressants on lithological particles

为减轻综掘工作面粉尘逸散对巷道环境的污染以及人员、设备造成的损伤,以济宁市金桥煤矿西翼轨道巷为工程背景,以可吸入粉尘为研究对象,研发一种以表面活性剂为关键骨架、以无机盐和高分子黏附剂为辅助材料的强润湿性、强黏结性的环保型化学抑尘剂。现场验证结果表明,该抑尘剂对于岩性颗粒物具有较好的捕捉能力,能有效降低巷道内可吸入粉尘浓度。

To reduce the pollution of the roadway environment and the damage caused by the personnel and equipment by the dust escaping from the fully mechanized driving face,a chemical and environmentally friendly dust suppressant with strong wettability and strong adhesion was developed based on the engineering background of the west-wing track roadway of Jining Jinqiao coal mine,and inhalable dust as the research object,with surfactants as the key skeleton and inorganic salts and polymer adhesives as auxiliary materials.The results of field verification show that the chemical dust suppressant has a better ability to lithological particles and can effectively reduce the concentration of respirable dust in the roadway.
