Design features of closed coal storage yard

As the state-specified environmental protection policy is becoming ever-increasingly stringent,the use of closed coal storage yards has become an inevitable choice of coal enterprises.For expanding the applicability of such a yard,an analysis is made of the design features of the yard,following an introduction to the structure of the domestic closed coal storage yards currently available,in a bid to provide the theoretical basis for reference in making design of such kinds of yards by coal-related design,engineering units or coal preparation plants.
