Research and practice on audio electric perspective detection technology of mine flood in Diandong mining area

In view of the complicated hydrogeological conditions of coal fields in southwest China and the lack of research and practice on the detection technology of coal mine flood，the research and practice of audio electric perspective detection technology in eastern Yunnan mining areas were carried out.The theoretical basis，technical characteristics and construction methods of audio electric perspective detection technology were studied.The engineering practice of audio electrical perspective detection technology was carried out at the first coal mining face of Yuwang Coal Mine in Diandong Energy.The location，distribution and water content of geological abnormal bodies such as water-rich area and geological structural belt within 100 m height of the top and bottom of the coal face were reliably detected.The drilling verification showed that the detection results were highly reliable.It provides a reliable geological basis for the prevention and control of the flood in the coal face of the first well of Yuwang Coal mine，and provides technical support for the precise control of flood in the first well of Yuwang Coal Mine and the realization of green and safe mining.The parameters such as the apparent conductivity value of the audio electrical perspective method obtained by research and practice fill the blank of the research and practice of the audio electrical perspective detection technology in the eastern Yunnan mining area.It can provide reference for the analysis of mine hydrogeological conditions under similar geological conditions and has important theoretical and practical significance.
