新景煤业15121工作面带压区水文物探研究OA

To ensure the safe production of No.15121 Face in Xinjing Coal Industry,this study adopted the mine direct current method and audio-frequency electrical penetration detection method to investigate the distribution characteristics of water abundance abnormal zones within the depth range of 0～90 m below the working face floor.Multiple low-resistivity abnormal zones were identified in the study.Combined with a comprehensive analysis of the geological and hydrological conditions of the working face,five key low-resistivity abnormal zones were delineated,among which No.5 anomaly was defined as the key section for water disaster prevention and control.The research provided important geological data and a basis for water disaster prevention and control for the safe production of the working face.
