Due to the impact and friction of coal bulk for a long time, wear groove side scraper conveyor is extremely severe. This significantly reduces service life mining efficiency conveyor. There an urgent need effective wear-resistant method address severe side. study aims investigate effects five factors (diameter, depth, horizontal distance, vertical arrangement angle) bionic pit structures on loss Wear tests were designed explore combination different three-body condition Response surface methodology (RSM) test results showed that increase in diameter loss. Increases distance depth Diameter have interactive effect The angle samples insignificant. optimal combinations are as follows: 1.62 mm, 9.01 mm 0.97 mm. reduction rate reaches 36.6% with structure. Combining results, morphologies observed analyze wear-resistance mechanism. function reducing contact area, storing particles metal abrasive debris, easing stress state samples, improving movement bulk. can provide basis design conveyor, prolong improve machinery equipment.
