Теоретические исследования бункер-перегружателей с гравитационной загрузкой

The formulated problem is to enhance roadway construction efficiency and environmental safety using continuous mining technology with batch-action bunker loaders. The object of the research is the bunker loader with the hydraulically driven batch-action carrier. For feeding the bunker loader, the proposed engineering solutions include the varied angle of chute to ensure gravity feeding. The method of determination of actual bulk volume in the bunker loader chute during gravity feeding is substantiated to develop an engineering selection procedure of its rational parameters. The main behavioral patterns of bulk material are found, the quantitative and qualitative relations are obtained to determine actual bulk volumes as function of inclination angle , type of material characterized with the repose angle  , chute surfacefriction angle  and internal friction angle  . The final mathematical model of the listed characteristics represents a system of equations in the form of an algorithm and a control flow chart. The testing and calculation data are analyzed. The physical pattern of the granular material behavior in gravity feeding of a bunker loader is studied. The research conclusions are drawn.
