Coal mine shaft concrete lining crack repair technology
TANG Minggao
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.
