【Abstract】 This paper, more systematically, introduces associated way and characteristics of displaced water pipe net in coal mine after best choosing, and also states the connection with the waste of energy and the associated way of displaced water pipe net.The author uses illustration for calculating to find the best diameter of the pipes,and makes use of the principles of equal flow in theory and efficient devices to determine and analyse the method of proper choice in the number of pipe lines in the displaced waterpipe net,and again lists the relationship in numbers between working pump and the number of lines in working pipe net. All this is chosen as reference in engineering.更多还原
