| 摘 要： | 针对淮南矿业集团丁集矿井表土层深厚、井筒直径又大、井壁受力复杂的特点,在冻结段井壁结构设计中首次采用了C60~C70高强高性能混凝土。通过对混凝土原材料选择,配合比试验,确定出合理的配制参数,并通过建立集中搅拌站,加工质量控制,使得C60~C70高强高性能混凝土在丁集矿井三个井筒冻结段井壁工程中得到成功应用。

| Abstract: | Aiming at the peculiarity of huainan mining group company Dingji mine,deep surface soil、wide diameter of well and complex force of wall of a well,C60～C70 high strength and performance concrete is firstly applied in the structure design of well of freezing part.After raw and processed materials of concrete is choiced and test of assort ratio is done,reasonable parameter of confect is confirmed.And after the centralized workstation is set up and the control of quality is strengthen,the application of C60～C70 high strength and performance concrete in the freezing part of three wells of Dingji mine is successful. |
