【摘要】 研究了不同分散性的防老剂甲对义马耿村矿长焰煤自燃的化学阻化作用。结果表明，防老剂甲对耿村长焰煤自燃有显著的阻化作用，且防老剂甲的阻化效果随其分散程度的增加而提高，使用分散剂的０．５ ％ 防老剂甲对煤氧化的阻化效果高于２０ ％ 氯化镁，仅比未使用分散剂的５ ％ 防老剂甲略差。使用分散剂后，防老剂甲的使用量和成本有较大程度的降低。更多还原

【Abstract】 H10The chemical separation results of antiager A with different dispersity against spontaneous combustion of longflame coal from Gencun Mine in Yima was researched.It was shown by the research result that antiager A has obvious separation effect on spontaneous combustion of the coal,and the separation effect can be improved with the increase of dispersity of antiager A.The effect of 5% antiager A with disperser can be higher than that of 20% magnesium chloride,only a little lower than that of 5% antiager A without disperser.With disperser added,the used amount and cost of antiager A can be cut down greatly.更多还原
