Abstract：To address the surplus coal slurry issue in the Shenmu-Weinan Coal Slurry Pipeline Project(designed capacity:10 million tons/year),caused by environmental protection restrictions in the Guanzhong region and insufficient absorption capacity of end-users(3.61 million tons/year),an optimized storage,loading,and transportation system for dehydrated coal slurry was proposed.Through combining the material characteristic analysis(particle size≤1.2 mm,moisture content 21%～28%,bulk density 0.75～0.92 t/m3)with practical experience from the first-phase project,an innovative system architecture was proposed using a"top-stacking and side-reclaiming circular coal storage yard+intelligent truck loading",overcoming technical bottlenecks in handling wet and sticky coal materials.According to the operation practice in three years,the system transported 20 million tons of dehydrated coal in total,which brought significant economic benefits for enterprises.The results can provide reference for large-scale project of wet and sticky coal storage and transportation.
