| 摘 要： | 在三山岛金矿新立矿区西风井的施工中，通过多开盐水泵、增加盐水循环速度，增加冻结孔个数、降低冷冻孔间距，增加盐水浓度、把盐水温度降低到凝固临界点等措施，顺利通过了第四纪砾砂富含卤水层。为工程和水文地质条件类似的工程，提供了宝贵的经验，值得条件类似的矿山借鉴。

| Abstract: | During the construct ion of western airshaft at Xinli mine area of Sanshandao gold mine, through them easures of open ingmore salt pumps, increasing the circulation velocity of saline, increasing the number of freeze-hole and reducing the frozen-hole pitch, increasing the concentration of salt water and make its temperature down to a critical point,successfully passed the quaternary gravel-rich brine layer. It provides valuable experience for the projects of similar engineering geological and hydro-geological conditions, and worthy of reference for similar mine. |
