摘　　要：为掌握沙坪煤业13103工作面带压开采奥灰突水危险性,采用综合物探及钻探法对底板富水性实施探测。结果表明,运用无线电坑道透视法发现5处异常区域均与工作面掘巷已探明断层、向斜构造重合;音频电透法与瞬变电磁法均探测出工作面底板富水异常区。结合钻孔探查得到3个重叠异常富水区,YC3、S1和Y1重叠区显示向斜轴部含水层具有高富水性和补给源,YC4和S2重叠区出水量小,但仍存在补给,局部富水区域有水害风险,YCS和Y2重叠区无水力联系独立含水层。该探测结果为13103工作面回采计划的制定提供地质资料支持。In order to grasp the risk of Ordovician ash water inrush in 13103 working face of Shaping Coal Industry Co.,Ltd.,comprehensive geophysical exploration and drilling methods were used to detect the floor water richness.The results show that the 5 abnormal areas found by radio tunnel perspective method coincide with the known faults and syncline structures in the excavation roadway of the working face;Both the audio frequency electropermeability method and the transient electromagnetic method detected the abnormal water-rich area of the working face floor.Combined with drilling exploration,3 overlapping abnormal water-rich areas were obtained.The overlapping areas of YC3,S1 and Y1 showed that the aquifer in the synclinal axis had high water-rich and recharge sources;the overlapping areas of YC4 and S2 had small water yield but still had recharge,and local water-rich areas had water damage risks;the overlapping areas of YCS and Y2 had no independent aquifer with hydraulic connection.The detection results can provide geological data support for the formulation of stoping plan of 13103 working face.
