In the coal mine transportation, the scraper conveyor chute is badly worn. However, the abrasion performance has not been well documented. In this study, the chute was wear tested under a single factor using a modified pin-on-disc apparatus, including normal load, sliding distance, bulk coal characteristics (water content, gangue content), and chute material. Experiments were also carried out with a simultaneous variation of these factors. Generally speaking, the influence of coal characteristics on the chute wear was obviously higher than that of normal load and sliding distance. An improved wear predict model was obtained taking the operational parameters and bulk coal characteristics into account. The wear mechanism involved micro-ploughing, corrosion, adhesion, and fatigue peeling.

在煤矿运输中，刮板输送机滑槽磨损严重。但是，磨损性能尚未得到充分记录。在这项研究中，使用改良的销钉盘式设备对滑道进行了单因素磨损测试，包括正常载荷，滑动距离，散装煤特性（水含量，脉石含量）和滑道材料。同时进行了这些因素变化的实验。一般而言，煤质特性对溜槽磨损的影响明显高于正常载荷和滑移距离。考虑到运行参数和散煤特性，获得了改进的磨损预测模型。磨损机理涉及微耕，腐蚀，粘附和疲劳剥离。
