为查明河北康城煤矿1905工作面顶底板、底板 H1火成岩及工作面范围内富导水性，根据现场地形地物条件，选择电测深对称四极装置沿工作面走向平行布设4条测线。经反演分析后，绘制出相应测线的视电阻率等值线图。依据9＃煤层底板标高线，绘制出9＃煤层顶、底板及 H1火成岩层视电阻率顺层切片三维图。综合分析表明，测区内富水异常分布不均一，西南部及东北部富水性相对较强，局部富水异常较明显，且在垂向上有较强的水力联系。在工作面布设前布置了钻孔进行验证。建议在工作面掘进过程中，针对圈定的低阻异常区段，开展超前探查和防治措施，以确保工作面安全掘进和回采。

In order to find out the water abundance and hydraulic conductivity in the roof&floor, floor H1 igneous rocks and working range in 1905 mining face in Kangcheng coal mine,according to the terrain and surface features,the symmetric electric quadrupole sounding device is used,and 4 parallel survey lines are arranged along the trend of the mining face.After inverse analysis,4 apparent resistivity isoline charts are drawn.Based on the floor elevation lines of 9# coal floor,the 3D figure of the apparent resistivity bedding layer slice of 9# coal roof,floor and H1 igneous rock are drawn.Comprehensive anal-ysis shows that the water-abundance anomaly distributes unevenly,and more water-abundance zones lo-cate in the southwest and the northeast part,and local water-abundance anomaly is obvious with strong waters connection in vertical.Therefore,before setting the working face,drillings should be arranged to verify the fact,or during the working face tunneling,the advanced detection and prevention should be a-dopted in the circled abnormal low resistance zones,to ensure the safety of the working face tunneling and mining.
