摘　　要：通过对华亭、张掖和神府三种煤进行单煤制浆、不同质量比的两种煤和三种煤配煤制浆实验,研究配煤对水煤浆性能的影响。单煤制浆中,各煤种配制的水煤浆黏度和稳定性差异较大,其中张掖煤配制的水煤浆稳定性最好,为13.11%,神府煤的表观黏度最小,为622m Pa·s,符合国家标准。配煤制浆中,华亭煤、张掖煤和神府煤以3:2:1的质量比组合制得的水煤浆稳定性最好,为9.59%,表观黏度为653.7m Pa·s,符合国家标准。配煤制浆的实验结果表明:由于煤种间相互作用的效果不同,配煤煤种的选择以及配比的不同,都影响配煤的水煤浆性能。Three different coals,Huating,Zhangye,Shenfu coals,were blended with each other in different proportions,and the effect of blending coals on the slurry ability and stability of coal water slurry( CWS) were studied. The slurry ability and stability of CWS prepared by the single coal were also researched. Results show that Zhangye coal have better stability,with the stability reaching 13. 11%,Shenfu coal have minimum viscosity,with the viscosity reaching 622 m Pa·s. Where as,the test on blending coal shows that when the Huating coal,Zhangye coal and Shenfu coal are blended at a ratio of 3: 2: 1,the slurry prepared has the stability reaching 9. 59% and the viscosity reaching 653. 7 m Pa · s. Blending coals can in fluent the rheology and stability of CWS. However,blended with the same coal,different coal type and blending ratio have different effects on the slurry ability and stability.
