The belt deviation is the most common fault when the belt conveyer operates, and the installation size precision and the daily maintenance are important to solve the faults. The maintenance of the machine is an extremely important and frequent work, which should be closely matched with the extremely frequent operations and overhaul, etc., and a professional person should perform on-duty inspection. The belt conveyer has the advantages of long conveying distance, large conveying capacity, small working resistance, convenience in installation, low power consumption, small abrasion and the like; the coal unloading device has the defects that an inclined roadway requires that the inclination angle is not more than 18 degrees when the coal unloading device is transported upwards, goods slide downwards when the inclination angle is more than 18 degrees, the goods cannot be loaded, and when the coal unloading device is transported downwards in an inclined mode, the inclination angle is not more than 15 degrees and is more than 15 degrees, namely when a belt stops, the belt driving roller stops rotating, but due to inertia, the belt moves forwards along with the coal unloading roller, so that the goods on the belt are piled on the driving roller; the other is that although the belt is stopped, the goods will slide down automatically due to large gradient and small resistance, the goods cannot be controlled, the goods piling phenomenon occurs, and the advantage is greater than the defect in the horizontal roadway.

Therefore, it is necessary to detect a failure of the belt conveyor, which has a long span, and when the belt conveyor fails, it is necessary to perform maintenance to determine which section has failed, which is time-consuming and troublesome.
