Optimization of Transportation System at Working Face Under Complicated Geological Condition

Under the complex geological conditions, with the development of high yield and high efficiency fully mechanized mining technology, the coal transportation in Hexi W11701 section was difficult to meet the needs of production. The article proposed different optimization solutions for the original transportation system. Results showed that the optimized scheme has the features of less occupancy of equipment, continuous transportation, safety production, orderly mining following by unloading device.
