摘　　要：针对桌子山煤田较特殊的煤系沉积基底和构造控水特征,在近年来研究区各矿奥灰水文地质补勘及专项研究工作的基础上,结合目前各矿防治水技术应用现状,分析总结了区内下组煤开采底板水害防治技术及理论研究方面存在的不足和亟需解决的关键技术难题,如沉煤基底地质成因、构造控水机理、含导水构造精细探查程度、有效隔水层厚度分布规律等。综合考虑目前防治水理论研究和技术应用现状,提出了研究区下组煤开采底板水害防治初步解决思路和防治技术措施,研究成果对桌子山煤田下组煤开采底板水害防治工作的有效开展具有重要意义和实用价值。Aiming at characteristics of coal sediment basement and water controlled by tectonic , on the basis of the work of Ordovician limestone hydrogeology additional exploration and special research in mines, shortage and key technical difficulties in floor water pre-vention theory and technology were concluded including geological factor of coal sediment basement, tectonic water-controlled mecha-nism, elaboration exploration degree of water-induced tectonic, effective water-resisting layer height distribution rule, etc.By com-prehensively considering theoretical research and technical application status of water prevention, initial solution and technical measure of floor water prevention in lower-group coalseam mining were present which had important significance and practicable value for floor water prevention of lower-group coalseam mining in Zhuozishan coalfield.
