Abstract: In order to improve the level of coal quality inspection and control, aiming at the problems of relying on manual operation, low efficiency and poor data accuracy in the traditional coal quality inspection mode, the application of intelligent acquisition system in coal quality inspection and control is studied. The intelligent sampling and preparation system has innovative points such as beltless fully sealed sampling and preparation integrated design, fully intelligent robot sampling system, and fully intelligent testing system, which can improve the accuracy of testing, optimize the allocation of human resources, and guide the adjustment of coal preparation process parameters. Taking Huangling No.1 Coal Mine as an example, the system can improve the accuracy of raw coal test, reduce the allocation of human resources, improve the guidance effect of coal preparation process and optimize the product quality in practical application. The research shows that the deployment of the intelligent acquisition and preparation system optimizes the coal quality inspection and control process, and significantly reduces the labor intensity and improves the working environment.
