When the 1# coal bunker is full, the main belt needs to be stopped, and the coal distribution hopper gate needs to be manually switched to the 2# coal bunker to discharge coal. Each time the bunker is emptied, the machine needs to be stopped for 3-5 minutes to complete the operation. The full-bunker emptying stop has become an important factor restricting the start-up rate of the main transportation belt. Once the main belt is stopped, it will also cause the stop of each team along the belt. The main belt needs 3-5 minutes to empty the bunker, and the mining team needs 10-20 minutes to start in turn. At the same time, the full-bunker emptying stop will also cause the heavy load start of the belt conveyor, damage the related equipment of the belt conveyor, and shorten the service life.
