As the mining of Duerping Mine gradually extends to the boundary of the mine field, the original transportation system can no longer meet the existing production and development requirements. In order to ensure the safe and efficient production of the mine, it is necessary to optimize and transform the raw coal transportation system according to the existing actual situation. The raw coal transportation system in the north area is relatively complex, and the transportation mode of ' centralized belt + mine car + bottom-hole yard unloading + main lifting belt ' is adopted. During the period, it intersects with the auxiliary transportation of the main roadway, and the transportation capacity can no longer meet the existing production demand. Therefore, the main transportation system in the north area is analyzed, and the scheme of continuous transportation of belt conveyor is proposed to cancel the transportation of raw coal in the main roadway and reduce the transfer link. After the transformation, the transportation efficiency of the main transportation system in the north area of Duerping Mine was improved, and the problems such as large interaction with the auxiliary transportation system were solved, which laid a foundation for the safe and efficient production of the mine.
