Analysis of Coal Loading Effect of Coal Cutter in Fully Mechanized Coal Mining Face with Dip Angle

Coal loading process is one of five processes of fully mechanized coal mine face, scraper conveyor processing amount and fully mechanized working face production rate was determined by coal loading effect directly.The production practical of longwall mining along the strike with large angle coal seam showed that coal loading effect decreased obviously with working face incline angle increased.Based on roller coal loading principle and working face dip angle，then the main factors that influenced coal cutter loading effect of longwall mining along the strike with large angle coal seam were analyzed.Roller coal loading effect was more better with downward cutting method then upward without arch spillplate，when arch spillplate was applied，the optimal coal loading effect could arrived with all cutting method.it suggests that coal cutter loading effect of longwall mining along the strike with large dip angle coal seam could be improved under arch spillplate application and optimized roller parameters and decreased chute height.
