立井井筒机敏混凝土实施技术及应用

Implementation technology and application of smart concrete for vertical shaft

葫芦素西翼风井井筒建井期间,在井筒井壁采用添加碳纤维的方法施工机敏混凝土井壁,在井壁布设电极进行测试,获取该段井壁在不同方向和不同位置的井壁应力和变形数据,实现了对冻结井筒井壁数据的远程监测和收集,并为适用于西部地区建井设计规范的编制提供了数据支持,为冻结法设计富水软弱基岩时井壁"优化"方法和参数提供了理论依据和实际验证。

In the west wing mining of Hulusu Mine,adding carbon fiber to smart concrete for mine wall,wall stress and deformation data in different direction and position were got,realizing remote monitoring and collection of frozen shaft wall data,which provided data support for mining rules in northwest of China,and the theoretical basis and practical verification for the ＂optimization＂ method and parameters of the shaft wall when the freezing method designed for water-rich soft bedrock.
