摘要
为解决我国能源短缺问题,两淮地区掀起了建国以来规模最大的新井建设高潮,此次开发均为深部资源,井筒穿越的冲积层深厚,为了降低井壁厚度,提高井壁混凝土的耐久性,筑壁材料采用了高强高性能混凝土,为了确保施工中使用的高强高性能混凝土既经济合理又强度可靠,对深厚表土冻结井壁的高强高性能混凝土进行了试验研究,并成功在淮南矿业集团丁集矿井建设中应用。
In order to settle the nation＇s problem of energy＇s scarcity, a wave of new mines＂ constructing of the largest scale has been starting in the north and the middle part of Anhui province since our country was built. The ongoing exploitation is all deep-level resources, and the alluvium through which the shafts drill is also deep. Therefore, in order to reduce the thickness of shaft lining and advance the wearability of shaft linings concrete, high-strength and high-performance concrete （HSAHPC） is adopted to construct the shaft lining. In order to insure the HSAHPC to be economical and strength reliably, an experimental research is done for shaft linings HSAHPC in operating conditions of frozen and thick surface soils, and the HSAHPC is suceessfully applied to the Dingji mine＇s shaft walls.
