Abstract: An analysis is made in the paper of the scheme for the building of the clean coal quality control system for coking coal preparation plant, with Matou Plant as an example, based on the technical means currently applied by coal cleaning enterprises for clean coal quality inspection, and in line with the characteristics of the central coking coal preparation plant. While setting up the quality control system, the scope of quality control is also defined by introducing the method of mathematical statistics, so as to ensure a highest utilization rate of resources and a maximized economic benefit while guaranteeing the up-to-standard quality of clean coal product.
