摘 要:介绍了赵固一矿、泉店风井、赵固二矿、顺河副风井、李粮店主副井等深厚冲积层冻结井施工的实践经验,得出冻结凿井技术水平和经济效益的提高主要体现在安全、快速施工的成果上;同时,从冻结方案设计、机械化水平配置、冻结与掘砌的配合等方面总结了深厚冲积层冻结段安全快速施工技术。Experiences of deep alluvium freezing construction was introduced, based on freezing construction practices of air shafts in Zhaogu No. 1 and Quandian Coal Mine, auxiliary air shafts in Zhaogu No. 2 and Shunhe Coal Mine, and Liliangdian main and auxiliary shaft. The paper pointed out that, the enhancement of freezing technology level and economic benefit was mainly manifested in the achievements of safe and rapid construction. The safe and rapid construction technologies of deep alluvium freezing section were summarized, from the views of freezing scheme design, mechanization level and the coordination of freezing and excavation.
