摘　　要：为了确定唐口煤矿2309工作面合理开采上限和留设安全煤柱,减少煤炭资源的浪费,需要准确测定该工作面的导水断裂带高度。采用经验公式预计和数值模拟的方法,对2309工作面导水断裂带高度进行了分析计算,其结果分别为46.2、48.1 m。运用"双端堵水器"技术,采用井下仰上孔的方法,实测了导水断裂带高度,其值为50.9 m。实测结果与经验公式预计值和数值模拟值基本相符,实测结果可靠。In order to determine the upper limit for the rational mining of 2309 working face and the setting of safety pillars in Tangkou Mine and reduce the waste of coal resources, it is necessary to accurately measure the height of the water-flowing fractured zone in the working face. Analysis and computation were conducted on the height of the water-flowing fractured zone in 2309 working face by using the empirical formula and numerical simulation method, the results were respectively 46.2 m and 48.1 m. Actual measurement was made on the height of the water-flowing fractured zone with the technology of ＂double-end water blocking device＂ and the method of underground upward holes, the result was 50.9 m. The measured results were basically consistent with the expected value of empirical formula and the numerical simulation value, so the measured results were reliable.
