一种钻孔隔温循环系统
摘要：
本发明公开了一种钻孔隔温循环系统，包括沿矿井井架圆周方向设置的多个隔温孔、清水泵组、清水池和连接管；矿井井架上每四分之一个圆周上的隔温孔依次串联组成一个隔温孔组，清水泵组通过连接管连接到清水池，清水泵组上设置四个供水出口，矿井井架圆周上形成的四个隔温孔组分别通过连接管连接对应的供水出口，每个隔温孔组通过连接管回流至清水池。本发明结构简单，使用方便，能够有效的维持井架基础附近的适当厚度的未冻带，通过在隔温孔内热水循环，保持足够的未冻带。
摘要（英）：

The invention discloses a borehole insulating and circulating system comprising a plurality of insulating holes arranged along the periphery of a mine derrick, a clean water pump unit, a clean water pool and connecting pipes. The insulating holes in every one quarter of the periphery of the mine derrick are serially connected in sequence to form an isolating hole group. The clean water pump unit is connected to the clean water pool through the connecting pipes. The clean water pump unit is provided with four water supply outlets. The four insulating hole groups arranged in the periphery of the mine derrick are connected to the corresponding water supply outlets through the connecting pipes, respectively; clean water from each insulating hole group flows back to the clean water tank through the corresponding connecting pipe. The borehole insulating and circulating system is simple in structure and convenient to use; an unfrozen area of proper thickness around a derrick foundation can be effectively maintained, and the sufficient unfrozen area is maintained by circulation of hot water in the insulating holes.
