Research and Application of Wet Concrete Spraying System in Coal Mine
In response to the problems of high dust in the working environment,high labor intensity of workers,low solidification strength and high rebound rate of dry concrete spraying in underground coal mine roadway,developed a new wet concrete spraying system.This system consists of main equipment such as shovel mixer,conveying pump and spraying robot.The prototype manufacturing has been completed,application tests have been conducted,and the test results have achieved the expected goal.
