| 摘 要： | 峰峰矿区九龙矿的隐伏突水陷落柱发育于奥陶系石灰岩含水地层，发育高度至石炭系大青灰岩、伏青灰岩。由于其发育范围小，又隐伏于可采煤层以下。一般勘探手段很难给予精确解释，导致矿井开采过程中发生突水灾害。通过对矿区隐伏突水陷落柱的治理工作实践，介绍了其探查及治理过程：按照”探治结合”的治理原则，首先采取对矿区工作面三维地震资料进行精细解释，然后以注浆钻孔定向钻探施工技术进行验证的方法，确定突水构造的类型和空间发育形态，进而实施注浆治理，达到堵截突水通道、保障矿井安全生产的目的。本方法的成功实践，为今后华北型煤矿突水灾害的治理工作提供了的范例。

| Abstract: | The hidden water inrush subsided column in the Jiulong coalmine, Fengfeng mining area is developed in the Ordovician limestone aquifer, the development height can up to Carboniferous System Daqing and Fuqing limestone. Since the small scale and lie concealed below the mineable coal seams, thus hard to interpret accurately by general exploration means, and bring on water bursting hazard during coal mining. Through mine area fathering practice of hidden water inrush subsided column, introduced its exploration and fathering processes. According to the principle of ＂combined exploration and fathering＂, firstly carried out mine area working face 3D seismic data accurate interpretation, then using grouting borehole directional drilling operation technique to validate and determined water inrush structure type and spatial development configuration, then proceeded to carry out grouting fathering, closed up inrush channel, finally coalmine production safety guaranteed. The successful practice of the method can provide a model for North China type coalmine water bursting hazard fathering works henceforth. |
