【摘要】 系统总结了人工地层冻结技术的发展及其在煤矿立井建设中的应用。针对我国今后将要在深厚表土地区建设大型煤矿的工程背景,提出了冻结法建设煤矿深立井需要解决的关键问题是深土冻土的基础理论研究、适用于深厚表土层的冻结壁设计、井壁结构设计以及深井冻结法施工技术。更多还原

【Abstract】 The development of the artificial frozen technology and its applicability in the coal mine shaft is summarized in this paper.In view of the background that our country will construct large-scale collieries in deep alluvium area, the key technologies which required in the freezing process to be used in the deep shaft are research of the basic theory of frozen soil for deep alluvium,designs of freeze wall and shaft lining structure that suitable for the deep alluvium,and the construction technology of freezing process in deep shaft.更多还原
