摘　　要：借助润湿热、接触角的测定及红外吸收光谱分析手段,对加入MO浮选促进荆的柴油与煤样的作用机理进行了研究分析,建立了MO药剂在煤表面的吸收模型,阐释了浮选促进剂能显著改善浮选效果的机理。The mechanism of diesel acting on coal after the promoter MO has been added was researched and analyzed by measuring the wetting heat and contact angle and using the infrared absorption spectrum. The electric charge distribution of surface molecule of bituminous coal with low volatile was calculated by means of quantum chemistry. The adsorption model of MO agent on the surface of coal was established. And the mechanism of improving flotation effect obviously using the promoter MO was explained.
