摘要(Abstract)：
煤层底板含水层注浆改造技术可以彻底根治底板水害。利用瞬变电磁技术探测煤层底板含水层的赋水性特征,确定工作面内注浆改造重点区域,指导钻孔布置,并在底板改造后检验注浆改造效果。其在焦作矿区的应用效果明显。
The grouting reconstruction technique of lower confining bed can be used to control the water hazard from coal floor.The transient electromagnetic thchniques can be used to determine the key region for grouting reconstruction,guiding the drill hole layout and detect the grouting effect.The application is confirmed of favorable effect.
