摘　　要：煤尘抑爆技术是防治煤尘爆炸的重要手段,抑爆技术核心是研究开发具有较好抑爆性能的抑爆剂。分析了煤尘抑爆剂的物理、化学、混合3种作用机理形式,并对现有抑爆剂进行了分类,提出了新型抑爆剂的基本特性,运用复配协同增效技术进行了抑爆剂的开发,选取Al(OH)3、聚磷酸铵和具有天然纳米孔结构的硅藻土为单体,通过合成得到3种复配型抑爆剂A、B、C;利用20L球形爆炸测试系统以爆炸特性参数为指标,对新型抑爆剂的抑爆效果进行了爆炸实验;结果表明,复配型抑爆剂较传统抑爆剂有更优越的抑爆性能,实现了协同增效。The technology of coal dust explosion suppression is an important means for coal dust explosio.nproofing. The core of this technology is to develop the inhibitor with effective explosion suppression performance. Firstly, the mechanisms of 3 inhibitors are analyzed, namely physics-based, chemical-based and mixture-based mechanisms. Secondly, the existing inhibitors are categorized and the basic property of the novel inhibitor is put forward. Then, the technology of synergistic mixtures is adopted to tap inhibitors by choosing 3 monomers （aluminum hydroxide, ammonium polyphosphate and diatomaceous earth） and synthesizing, and finally get 3 new inhibitors A, B and C. Utilizing 20 L spherical explosion test system, based on the index of parameters of explicability, the effect of the novel inhibitor is verified by explosion testing. The results indicate mixtures of inhibitors obtain good results, realize synergism and perform much better than traditional inhibitors.
