Abstract
To address the issue of low core recovery rate of the the curtain grouting project in the adjacent mining ar-ea of Datengxia Gorge Water Conservancy Hub,a technology for improving the core recovery rate in karst borehole sections was proposed through QCC activities.Firstly,the karst geological conditions of the Dafengxia Gorge Water Conservancy Hub were summarized;Then,a technical system for improving the core recovery rate in karst borehole sections was established comprising the core steps of current status investigation and target determination,cause analysis and identification of critical factors,and formulation and implementation of countermeasures;finally,the effect of the systematically improved core sampling technology for karst strata was evaluated.The engineering prac-tice results show that following the QCC activities,the core recovery rate of the curtain grouting project in the adja-cent mining area of the Datengxia Gorge Water Conservancy Hub increased from 54.3%to 62.8%,and the compre-hensive ability of the QCC members was also significantly enhanced as well.关键词
