| 摘 要： | 为准确测定太平煤矿某工作面开采的导水裂隙带高度、确定工作面合理开采上限,运用“双端堵水器”技术, 采用井下打仰上孔的方法, 实测了覆岩导水裂隙带的发育高度。观测结果表明, 该工作面导水裂缝带发育高度为23.85 m, 裂采比为13.2。实测结果与理论预计值和数值模拟值基本吻合,相互得到验证。

| Abstract: | In order to accurately determine the height of water-flowing fracture zone, as well as the upper mining limit in some working face in Taiping Coal Mine, a technology with “double-end shutoff device” was adopted by drilling upward holes under the coal mine to measure the real height of water-flowing fracture zone. The results show that the developed height of water-flowing fracture zone in the working face is 23.85 m, to which the ratio of the mining thickness is 13.2. The practical measurement is basically consistent with the theoretically expected and numerical simulated values, which can be verified by each other. |
