Abstract: The design of the rainwater system of the traditional coal preparation plant generally focuses on the aspects of flood control and drainage, and the low-impact development of industrial plant and water resource cycle are rarely involved. In response to various national policies in sponge cities, promote the application of low-impact development concepts in coal preparation plants, explain the design principles of low-impact development in industrial plants, study on the design parameters of rainwater systems, and deeply analyze the design points of various low-impact development measures, and analyze and summarize the effects of low-impact development. Through the low-impact development of the coal preparation plant, it can effectively realize the functions of reducing the peak value of rainwater runoff, controlling the annual total amount of rainwater runoff, strengthening the water ecological cycle and promoting the utilization of rainwater.
