In coal mine transportation,the chute of scraper conveyor is severely worn,but its wear performance is difficult to effectively record and evaluate.For this purpose,an improved pin plate wear testing machine was used to conduct single factor wear tests on the chute,including normal load,sliding distance,loose coal characteristics(moisture content,gangue content),and chute material.The results show that the influence of coal quality characteristics on chute wear is significantly higher than that of normal load and sliding distance.Taking into account the operating parameters and loose coal characteristics comprehensively,an improved wear prediction model was obtained.By simultaneously changing the testing parameters and using an improved model to explain the results,it is shown that considering the operating parameters and loose coal characteristics has a high accuracy in predicting the wear amount.
