三盘区运输巷顶板淋水特征分析及防治方案

Characteristic Analysis and Prevent ion on Roof Water-Spray ing in Transportation Roadway of No.3 Panel

针对伯方矿三盘区运输巷在掘进过程中顶板淋水较严重,多处顶板发生离层,局部出现冒顶,严重影响行人和运输安全等问题,为防止发生水害事故,笔者通过对防隔水煤柱的可靠性进行评价和物探验证,对顶板淋水特征进行分析,确定了淋水补给来源和通道,结合矿井生产实际制定了防治方案,并实施治理。实践证明,对充水水源和通道判断正确,治理方案效果显著。可为同类地质和水文条件下的顶板淋水治理提供借鉴。

In the excavating process of the transportation roadway of No.3 panel in Bofang Mine,there were serious water spraying roof,multiple roof separation,and regional roof caving,which severely affected pedestrian and transportation safety.In order to prevent water disaster,the authors analyzed the water spraying features,determined the sources and channels of water supply,formulated the prevent ion and control plan,and implemented it,based on the evaluation and geophysical verification on the reliability of water prevention coal pillars.Practice has proved correct judgment of the water filled water source and channel as well as remarkable effects of the treatment plan,which could provide a reference for the water spraying treatment for the roof un-der the same geological and hydrological conditions.
