摘　　要：煤炭自燃造成巨大的能源损失和环境灾害,为减少煤炭自燃,本文从分析采空区高硫煤层自燃机理入手,研究了凝胶阻化剂的综合防火机理,自主研制了新型凝胶阻化剂,在凝胶阻化剂的基料水玻璃中加入了石灰石。基于石灰平等互利高硫矿中的硫发生化学反应,从而从根本上降低了高硫矿的吸氧能力抑制了煤层的自燃发火。通过在矿山中进行应用,结果表明,该阻化剂能有效地阻止煤炭自燃,并且成本低廉。The coal spontaneous combustion can cause great loss of energy sources great environmental disaster. In order to decrease the coal spontaneous combustion, the coal spontaneous combustion mechanism is analysed firstly in this paper, and then, the integration fireproofing mechanism of gel inhibitor is studied, and a new kind of gel inhibitor is manufactured. By adding the carbonate of lime into the potassium silicate, the gel retarder can react with the sulfur component of te high sulfur coal, decrease the capability of oxygen-absorption, so as to suppress the spontaneous coal fire. The new type gel inhibitor is applied in coal mine and the results show that the gel inhibitor can prevent and extinguish the fire effectively with lower cost.
