地面井下联合布置的新型降温系统设计研究
Design and research on a new cooling system with joint arrangement of ground and underground
摘要
Abstract
If the cooling system is not considered or the cooling capacity is not adequately considered in the initial design of the produc-tion mine,it is difficult to increase underground cooling capacity in the later stage due to constraints of pipeline inside the wellbore.A new cooling system layout design was proposed,which combined surface and underground refrigeration.The chilled water sent to under-ground was first cooled and then partially used as cooling water to increase the temperature difference of circulating water.While keep-ing the wellbore pipeline unchanged,its cooling capacity can be increased.The feasibility of the joint cooling system was demonstrated through design examples.关键词
