针对煤矿管道内部腐蚀严重的问题，分别在高浓度和低浓度煤泥水工况下，对管道腐蚀磨损率进行数值模拟，并对比了普通钢管、高锰钢管和聚脲内衬管道的抗磨损性。结果表明：随物料浓度的增加，管道磨损率增大，且普通钢管和高锰钢管内部磨损量分别是聚脲内衬钢管的2.32倍和1.49倍，内衬聚脲的钢管内部磨损量最小，管道内衬聚脲材料有利于增强管道的耐蚀性和耐磨性。

In view of the serious corrosion in coal mine pipelines, the corrosion wear rate of the pipeline was numerically simulated under high and low coal slurry water concentration conditions, and the wear resistance of ordinary steel pipe, high manganese steel pipe and polyurea inner pipe was compared. The results show that with the increase of material concentration, the wear rate of the pipe increased, and the internal wear of ordinary steel pipe and high manganese steel pipe was 2.32 times and 1.49 times that of polyurea-lined steel pipe, respectively. The internal wear of the steel pipe with lining polyurea was the smallest, and the polyurea material lining pipe was beneficial to enhance the corrosion resistance and wear resistance of the pipe.
