摘要
通过对煤矿立井混凝土井壁裂缝产生原因的分析,针对不同性质的裂缝进行了系统分类,并提出了相应的修补措施.这些措施消除了井筒整体结构存在的安全隐患,并显著提高了井壁结构的耐久性能和防水性,可为类似工程设计及施工提供有益参考.
Abstract
Through the analysis of the causes of cracks in the concrete lining of coal mine shaft,the cracks of different properties were systematically classified,and the corresponding repair measures were put forward.These measures eliminate the safety hazard of the whole shaft structure,and signif-icantly improve the durability and water resistance of the shaft lining structure,which can provide useful reference for similar engineering design and construction.
