摘　　要：本文以煤矿井下采掘工作面高温高湿的特殊作业环境为基础,选用2-丙烯酰胺-2-甲基丙磺酸和二甲基二烯丙基氯化铵作为基料,以过硫酸铵和N,N'-亚甲基双丙烯酰胺作为引发剂和交联剂,选用甲基葡萄糖苷十二烷基酯作为表面活性剂,研制出在煤矿井下工作面中使用的新型树脂型抑尘剂。该产物有效减少了井下采掘工作面的产尘量以及二次扬尘,降低了煤尘对井下工作人员的身体危害以及工作面爆炸的危险指数。In this paper,based on the special working environment of high temperature and high humidity in underground coal mining face,2-acrylamide-2-methylpropanesulfonic acid and dimethyldiallylammonium chloride were selected as the base materials of the product,N,N’-methylene bisacrylamide is used as initiator and crosslinking agent,and methyl glucoside dodecyl ester is selected as surfactant,a new resin type dust suppressor used in coal mine working face is developed.The product can effectively reduce the dust production and secondary dust in underground mining working face,and reduce the physical harm of coal dust to underground workers and the risk of working face explosion risk index.
