Abstract: The mineral well drains system was an importance to guarantee mineral well safety produce. At safety with circulate efficiently, in order to increase the synthesize efficiency, decrease the exhaust water electricity consumes, the network of pipes was reformed based on the economic current velocity in net, making the total of the expenditure on construction and circulate minimum. Different tube path and draining mode were contrasted and analyzed in detail, to study and analyze how to increase the circulate efficiency of mineral well drains system and tube net. The study indicates that when the new replace drain pipe path diameters are at 1 inch above, and more tube worked together, the efficiency of water pump and tube net obviously increased.
Key words: network of pipes characteristic; economic current velocity; efficiency
