双鸭山矿业集团公司东荣三矿东风井于1994年1月8日掘进深219m时,冻结管断裂,漏失盐水融化冻结壁,造成透水、涌砂淹井。该矿把测温孔改为冻结孔进行强化冻结,经过90d的强化冻结,透水“窗口”闭合,达到了设计强度,将事故损失降到最低点。 When Dongfeng well of Dongrong No.3 Mine of Shuangyashan Mining Group Co., Ltd. was dug 219m deep on January 8, 1994, the freezing pipe fractured and the salt water was lost to melt and freeze the wall, resulting in flooding and flooding of the well. The mine to the freezing hole thermometer to freeze, after 90d of intensive freezing, water “window ” closed, to achieve the design strength, the accident will be reduced to a minimum.
